I have tried unsuccessfully from many sources to find a solution for my
problem while recording from VHS. I hope this list can help.
The bottom of the picture I am receiving from the VCR has a wavy,
pulsating line. I have tried both mythtv and ptune record with the same
result.
Someone said that it was because of the 480 scanlines coming from the
VCR. He suggested using the crop filter in mythtv. However this does not
work with my pvr 250 card.
I did an ivtvctl -a and noticed that in VIDIOC_G_FMT the Video Capture
height is 480. I am not sure if this is a measure of scan lines or
something else. Under VIDIOC_ENUMSTD for NTSC the frame lines are 525.
Can this number be changed to correspond with the scan lines from the
VHS? Is there a connection?
Suggestions greatly appreciated.
Gary
