Hi Guys - I'm new here, and this is my first post.

I've got a dVico 4130SH (australian model), and am having a bit of a problem with video playback. The 4130 has the Sigma Designs EM8623 chipset.

When playing back standard MPEG2, all is fine... When I playback h.264 and other mpeg-4 files, the video is extremely unnatural. Even though the source is only 24fps, the video looks overly smooth. Almost like a handycam when shot at 1000fps... Panning from right to left, or left to right, looks particularly strange. It almost looks like there's an unlimited number of frames as the scrolling is absolutely perfect.

It sounds like it should look great, but it's not.. It looks really strange and makes the movies look like they're shot on cheap handycams..

The problem is obviously something to do with the decoding of MPEG4 files, but I'm unsure of a solution. Most of my files are encoded by myself, so if there was a setting or type of file that would fix the problem, I'm happy to change my ways.

I've got a mate with a popcorn hour (8635 chipset) and it does not appear to have this problem.. I can't be absolutely sure this is the reason though, as all of his files were high-def and most of mine are standard def...

Any ideas? I would be most grateful if anybody else has noticed this and has a solution.

Cheers.
