Strange Capture Interlace issue

[SaSi]

I have been capturing TV broadcasts with the Pinnacle PCTV deluxe. Lots of problems with the device, but once you make it work, captures were excellent.

I was capturing interlaced, Top Field First at a high bitrate and then after editing re-encoded to MPEG2 at TTF and interlaced. DVDs worked out fine.

Unfortunatelly, the device broke, so I reverted to my ASUS ViVo card and Mainconcept capture.

Again, I captured interlaced, Top Field First and continued the process in the same way.

However, DVD playback was flickering. The bottom 1/3rd of the frame was flickering while the camera was panning.

I tried to re-encode to MPEG-2 with Bottom Field First. Again the same result, although now the top 1/3rd of the frame had flicker while panning in the same parts of the movie.

I then tried to de-interlace with VirtualDUB and re-encode to MPEG-2 as progressive.

This time, the playback on the DVD player was almost perfect. Not as good as my previous interlace captures-interlace encodings but certainly viewable.

Can anyone give any idea as to why this is happening?

Nobody seems to have any comment on the issue.

I have tried the capture with Mainconept doing the de-interlace during capturing, and the result is much better than VirtualdUB de-interlace, however movie movement is still inferior to the original broadcast or the Pinnacle capture.

I also tried to capture with VirtualDUB using hufyuv. After MPEG2 encoding and authoring, the results are the same. Interlaced captrure playback causes severe flickering on the TV.

So, I guess I have a more generic problem than Mainconcept capture.

Any ideas or suggestions?
