VERY STRANGE problem

[Dwight]

I tried recently to capture a tape (this is not strange itself)..
it plays normally on television..the auto-tracking of the vcr
works wonderfully on it. I plug the vcr to my computer (composite rca)
and play it in my tv-software (ChrisTV) and it still plays normally.

Now I open Virtualdub and put it on overlay in capture mode and
the same video is horribly out of track...twicthy on the sides and
capturing is impossible. Why oh why is the tracking totally
out of bounds on Virtualdub (also on Avi_Io) ?

I'm running out of multi-segment capture supporting aps to try .....(well I've tried 2 so far only)

Oh yeah, manually tracking does not work at all. I tried other tapes
and they all worked fine..., but it's still odd that the tape plays normal
on other applications + on the television.

Any ideas to why this is happening in virtualdub ?

[Dwight]

So nobody else has had this problem ?

I don't think it's the tracking of your VCR that's the problem, is it plays back on a TV fine, then there's no reason for it to change in Virtualdub.

I wonder, this wouldn't be an NTSC Tape by any chance ?

What Format are you trying to capture in, PAL, NTSC ?

[Dwight]

I capture PAL. All my tapes are PAL. This even happens
with stuff I've recorded with the VCR. Really annoying.

what is CPU utilisation shown by Vdub on capture?
how many dropped frames you have?

[Dwight]

Well, since the video shows up screwed up and out of bounds
on OVERLAY (I'm not capping) cpu usage isn't show.
Capturing video like this naturally results into a horde of dropped frames.
(so I don't do it)

With normal 'working' tapes I don't drop frames (usually cap 640 x 576, never dropped at this resolution)

But I doub cpu usage or frame dropping really has anything to do with the problem I described above, which appears to be software related

[Dwight]

Well, I have now tried three diffent vcr's and have to say...what's up with Virtualdub and Avi io...I can only wonder at this thing.

VIRTUAL VCR shows the video normally, but this does nothing for me.. as far as I know it does not support multi-segment capture ?
