I've been capturing with the Pinnacle PCTV USB card (one of the good ATI card clones), and so far I've been happy with the results. However, I've been over those weak signal recordings where image quality was not the most important factor but rather the use of a losslecc video codec.
Then, recently, I got to record good signal (despite some being second-generation copies) where I expected the EH50 lineTBC feature to do its thing. Yet... I'm still getting jagged lines/contours.
Here are the examples. Sorry for the large filesize, but they are the original FFV1 capture files so that all artifacts are shown.

Panasonic EH50 DVD recording:
What I beginning to realize is that captures made with conventional low image sharpness masked the jagged lines of analogic recordings. The ATI clone card is letting me see them...?
The fact that I'm getting the same results with the non-lineTBC Sony RDR-HX710 is making me suspicious and rather depressed.
Is it really a malfunction or is it the case of the EH50's lineTBC not being up to standards compared to S-VHS's lineTBC?
