My bad. Pinacle gave the no input error. The AV cables are split.
Well theres a real lack of info here, but instead of just saying it again ill ask a million questions
Did the recording setup change at all from HDTV -> other tv? aka: did you split the cables for both and never use the AV out for both?
Have you gone back to the HDTV and it still works?
I assume you have it setup like this:
Gamecube cable -> splitter -> one cable to comptuer and one cable to tv
If so, have you tried swapping the cable to tv between cable to computer?
Does your computer recognize that there is something plugged into it in the first place?
How is it connected to the computer? AV -> Usb or some other way?
What actual recording device are you using?
I noticed you are in the netherlands, is it correctly setup to record pal 60hz?
You can still see the game on the tv right? just not on the computer?
Have you tried turning the splitter aswell?
Have you tried other software for recording? if so, what software?
Is the tv flickering/looking funny at all compared to normal?
Thats about all the questions i can think of for now.
