I have been successfully capturing old tapes using the Panasonic EH50 (PAL) as the lineTBC passthrough.
However, I have a few poor signal recordings where I think lineTBC is doing more harm than good. I say this because when playing straight from the VCR the image is far more stable.
However, I was wondering if there are avisynth filters that can restore such issues, line frames "jumping around", image "wobbling" and such.
I have the link for the video sample:
