JStrider : I understand that they have a small wire, but all that is for is to save space on the card itself, it really does nothing to stop the static from comming through. The capture card I use has about a 1.5" round cable comming from the comp using a port much like a printerport. the wire is completely shielded and uses a Filter to stop most cross contamination. Every soo often I still get some issues but there totally unnoticable to someone who is not looking for them.
As I have said using a normal vid card is fine for the majority of people, the only reason I mentioned that is because there are some image quality gurus that want there Video output to look like some HD Movie, witch it wont for a good while yet.
Anyway I would suggest only looking at the high end breakout boxes if you wanted to also get into Digital Video. You could take a look at some of the cheaper products made by Dazzle or some other consumer manufacture. Also the AIWs do have a better quality output then any other consumer video card I have seen. If you were to do something I would suggest what meanSpleen
suggested. You should be able to get more bang for your buck if you went the rout of a small form factor case such as a shuttle and picked up a AIW 9700 PRO or some other card. That would allow you to play most games now quite deciently as long as you got a 2.0ghz+ CPU and as he said it would make a wicked stereo if you had a hometheatre system. The AIWs also come with a remote witch would allow you to do everything from the comfort of your couch/chair
About the DVD, as long as you dont try and record the DVD you should be fine. I have had my system hooked to my TV for quite some time now and it works fine for any DVD I have used. However if I was ever to go and try and record the DVD, even one I made myself (A wedding that I didn't want to have to re-record everything) Still caused issues when trying to record on my VCR.
One more tip, whatever you do get a wireless keyboard / mouse, nothing pisses me off more then having to get up and fix something on my comp. (yeah I am lazy as hell)
