After reading your post, I tried to make sure what I said was right by testing. Now I am not so sure anymore
All cards I have tested allow you to change TV standard on the "Capture" portion regardless of the tuner format. That was why I thought any of the cards should work. These cards include ATI, Hauppauge, etc.
However, a moment ago, I wanted to make sure, so I hooked up a VCD player to the Composite video input of my ATI All-in-wonder card. It turns out, the player I have been using converts PAL to NTSC before outputting to the TV card (or TV set - I should have known, since that is how I usually play those PAL formatted VCDs, i.e. from the player directly to NTSC TV set). So, inspite of my believe that it should work, I do not have real test to prove it
. Sorry.
It would probably the best to find out from the manufacturers. Emailing ATI or Hauppauge TechSupport for information probably is the best way to go.
