You don't need a TV tuner for that. A TV tuner is for watching TV on the computer. What you want to do is treat the TV like a second monitor.
And might I suggest something like XBMC to the disaster that is Windows Media Center.
Hi. I've never done this before, but I know if anyone can help, it's CNET ppl. I don't know how I got here, just searched around. I don't knw how to get back and follow this. I'm not as computer illitermate as you may think but I'm not used to doing this/forums. Here's my sitch, I would GREATLY appreciate any help I can get:
I've got a less than a yr old Gateway/emachine DX4720. I've got a new LG 32LH30 flat screen HDTV. I have the HDMI cable. I want to connect them so we can watch downloadable movies, ball games etc. Widow's Media Center claims it can't find a tuner in my computer. The computer company said that this model computer came with an installed tuner but not the driver. > They emailed me the driver and I couldn't install it. A fried came over and got it to install. It locked up my system so badly we had to re-install Windows (Vista) bcuz I couldn't find my paperwrk to tell me what my Bios-password was and I could't bypass it. So how do I find out what kind of tuner I have, how to make it work and get this thing connected to the TV?
