Flickering signal issue - Tilted Forum Project - TFP - Sexuality, Philosophy and Political Discussion

Trying to turn old VHS (PAL) tapes into NTSC DVDs. My question isn't about authoring, though, but capturing.

As I live in the States and everything's NTSC, including the VCR, I had to purchase a second-hand multi-format VCR, one that's built by Samsung (model SV-S97). I have it hooked up to my Radeon 9000 VIVO card via composite cable.

The VCR automatically detects the format of the tape. When I play one of the tapes, it says PAL AUTO on the display. I have ATI's VideoIN set for Composite and PAL-B, currently.

The problem is that the video preview (and capture!) looks extremely flickery. You can tell that the colours are displayed OK and all that, and for a second or so it plays fine and then it's a flickering mess that looks like the video feed is constantly getting overexposed or something.

I captured a short clip to demonstrate, it is located at http://www.jella.net/bin/flicker.wmv

I am thinking this might be an issue with ATI's capture drivers. I have updated them but am not sure if it "took".

I have also tried all the signal format options VideoIN has, such as PAL-B, PAL-D, PAL-M, etc. Nothing helps.

I'd welcome any ideas.

I have no experence whit this, but perhaps you might try a lower imput signal level.
If you play on a TV does it render correctly?

I've done about 20 or so home DVDs, all in NTSC. I use Ulead Movie Factory, VideoStudio, Sonic MyDVD, and usually the preivews show jittering. I went a head and burned test DVD and it played back just fine in the DVD player (not computer). I suggest you burn a test DVD and see if the playback still looks bad.

Yeah, I've done quite a bit of these too, but always in NTSC...this time the issue seems to be with something else though...
