Just acquired both the Asus TV FM Tuner and the WinFast 2000XP to make comparisons on AVI Huffyuv captures at full size and also compare quality qith the Canopus ADVC-100.

I conducted some very interesting tests (Using composite, S-Video for all 3) and I'll probably post some of the screengrabs if people are intersted to see the results.

However, on both the Winfast and Asus cards I got some weird scan lines (not even a full line actually) that was somehow 'shifted'. This is not due to a source problem (VHS in this case, but DVD grab had same problem), and the ADVC did not produce that artifact. Check the screengrab below (detail, not full frame).

Interesting thing is that this 'half scan-line' in the middle is not even from the same frame where it appears. Not a big deal if this happened once every minute but this is every 10 frames or so...

Anyone has a clue or had the same problem? Couldnt find anything on this anywhere...
