Watch Asher from Toronto, ONT CAN Comments

Asher's parents are getting a new TV and he gets to choose what he wants. There's not a lot of TVs to choose from, however. He's looking at the LG 55" 120Hz 3D LED Smart TV for $1200. Leo says that's a good TV. He also adds that the 120Hz isn't all that important: in fact, it can create a "plastic" look. It's still a good choice, though.

He's also looking at a Samsung 60" Plasma. Leo says that's comparable. The only real difference is where the TV is going to be located. For a plasma, he'd want to be in a darkened room. If he can do that, it is better. If he has to put it in a room with ambient light, LCD may be a better choice. Since Asher can't darken the room, the LG LCD is a better solution.

Watch John from Van Nuys, CA Comments

John has a PC that runs Windows XP and he can't view videos that are sent to him through email. Leo says that it's likely a codec issue. He recommends downloading VLC Media Player. It can play pretty much anything. But the real problem is that after April 8th, Microsoft will stop supporting and updating Windows XP with security patches. So John's computer will be vulnerable to attacks. Leo says that's a cause for worry and John should take it off the Internet before April 8.

Watch Mike from Realto, CA Comments

Mike has an older HP computer running Windows Vista. Can he put an SSD in it to speed it up? Leo says probably not. Older machines aren't fast enough to handle the speed of an SSD, which is rated for SATA 2. So unless the PC has a SATA 2 connector, Mike won't see any benefit at all. With the cost of an SSD, he would be better off getting a new computer. Of Course, he could also just upgrade to Windows 8 and get a boost that way.

Watch Tom from Warren, OH Comments

Leo says that the domain name server (DNS) is basically the phone book for the internet. When you type in an address, the DNS then takes that address and looks up the actual IP address of the website. It's numbers separated by periods. Tom can change his DNS on his computer quite easily. On the Mac, it's in the network settings of OS X.

To configure Mac OSX, Tom should go to System Preferences > Network, and select the connection he wants to configure. Then go to Advanced, and choose the DNS tab. Click the + sign at the bottom of the DNS Servers box, and enter the 3rd party DNS server settings. Then click OK, and Apply.

He'll have to change it for each interface. That's why Leo suggests doing it through the router instead. Leo recommends OpenDNS.com. It's faster and is more secure for blocking sites he doesn't want his kids to see.

To see some in depth tips on configuring DNS, check out this episode of Know How, hosted by PadreSJ.

Watch Estaban from Victorville, CA Comments

Estaban's old film camera broke, and now he's looking to move to digital. $500 is his budget. Leo says that's a great budget. Leo likes the Sony RX100 point and shoot. It's compact and has a zoom. It also has a large 1" sensor, which will give him far better photos. It lets in more light as well, so it's better in low light.

For DSLRs, the Canon EOS Rebels are great.

A great micro 4/3s camera is the Sony NEX 5.

If he's the guy always taking pictures, getting the most advanced camera he can afford is a good choice. Estaban should check out the reviews at dpreview.com and at CNet.

Watch Ben from Oxnard, CA Comments

Ben has an old XP machine and is thinking of installing Ubuntu Linux on it. Leo says he can do that, but he could also upgrade to Windows 7 or maybe even Windows 8. Ubuntu is a great OS, but he won't be able to use his Windows apps with it. Windows 7 is a lean, mean OS that can run on older machines quite well.

Watch Nick from Northridge, CA Comments

Nick wants to find out how to get started in learning how to code. It will take about a year to learn and become adept enough at coding to try and find work doing that. Nick already has certifications though, and he's in a good place to start. Leo says the worst case scenario is he'll just have fun doing it in his free time. Knowing how to code won't guarantee a huge success like with WhatsApp, and in fact the coding is the least of what they did. What made that app succeed is the design and user interface of it.

There are a number of sites that teach programming:

There's a book that was written by MIT and Duke University for beginning coders. Leo thinks this is the way to learn, and it's free to download. He can get it from htdp.org.

Watch Michael from Diamond Bar, CA Comments

Michael needs a camera to install in his car that has radar. Leo says that it's probably best to go to a car installer about that since it's more than just buying a camera. It's not only the camera, but the screen itself. So Leo advises letting a professional handle it. The chatroom says that Garmin makes one called the BC20 that wirelessly connects to GPS devices.

Watch Michael from Diamond Bar, CA Comments

Leo says that the cheaper tablets are usually cheap and don't have the capabilities of a slightly more expensive tablet such as the Google Nexus 7. Leo also says that apps like TuneIn Radio is great for getting stations all over the world. iHeartRadio is another radio app.

Watch Josh from Irvine, CA Comments

Josh has a Galaxy S4 that he likes, but the music widget keeps coming back and he hates it. Leo says that's not unusual. There's usually a default music player that Samsung uses. Leo says he can change the app on his lock screen in the display settings. That won't stop it from launching, though. Leo says one of the reasons he stopped using the Galaxy S4 is what he calls "Samsung interference."

The chatroom says all he can do is root it, install Titanium Backup and then freeze it. Another solution from the Galaxy S4 forums is to disable the app, and stop notifications. It should stop auto launching.

Samsung also sells a pure Google Play version that doesn't have all that nonsense. Leo hopes all of this will change with the S5, which will be announced Monday at Mobile World Congress.

Watch John from Orange County, CA Comments

John is going digital in his company, and he's bought several old Motorola Zoom tablets for his employees. He wants to know what security software he can install. Leo says first thing is to update the Android software to the current OS, Kit Kat. He can also set his password and PIN to only allow 10 tries. He can also install Lookout to remote wipe it should it get lost or stolen.

Watch Naomi from Denver, CO Comments

Naomi has been running SpinRite to repair a failing hard drive. Leo says that SpinRite fixes the lowest level problems of bad sectors. It will try and read them and if it can't, it'll copy the data off and move it, then mark that sector unusable. It won't stop until it reads it, which can take weeks. She did that and now it won't boot up. Leo says to get the data off the hard drive first by booting to a CD or by using another PC to read it. Then transfer the drive and make it a USB external drive. Then wipe the drive and reinstall Windows. Better yet, just get a new drive because it's starting to fail.

Watch Brett from New Jersey Comments

Brett bought a Google Chromecast and he loves it, but it needs more apps. Leo says that the SDK has opened up and he expects apps supporting Chromecast within six months. Patience, It's coming. But even as it is now, for $35, it's a bargain.

Watch Lee from Big Bear, CA Comments

Lee wants to know how to resize images with a right click in Windows. Leo says IrfanView is the app for Lee. It does a great job and will appear on in the right click menu after he installs it.

Watch Michele from Los Angeles, CA Comments

Michele is thinking about getting the Samsung Galaxy Note III as her next Android phone. Leo says he loves his Note III, but Samsung has junked up the Note and other phones with a bunch of bloatware. That may not bother her, though. It's certainly worth heading over to her wireless store to try it out.
