HELP, tv card lags

i bought this: http://www.newegg.com/app/ViewProductDesc.asp?description=15-116-616&depa=1 its a tv card with composite in on the back. i installed it everyting worked fine and the tv and radio works fun. BUT when i plugged my gamecube into the composite ins it lags tremendously. not the actual game but when i move my controller i can literally count 2, 3 seconds before the game responds to what i did. why is this?

 

Did you try upgrading the drivers? More often than not, the drivers that come on disk are slightly out of date.

 

i updated the drivers and applications and reinstalled wintv2000 (latest version). still same thing. its not like its just vid the audio lags too, but in sync with the video

 

does anyone else have a console hooked up to their tv card?

 

I did, but the audio separation was killing me. Do you use onboard Audio or a PCI audio board? Usually the onboard audio can cause a lot of separation between the video and audio.

I also have connected my Gamecube to my TV Tuner, but it never gave me the same problem of latency with the TV card. But it also may be because of the TV Tuner card, which is a Radeon TV Tuner card (I forget the model).

 

the audio is fine and it runs right along with video. just pissed off spent like 140 on the card and so far it sucks.
