when I load an uncompressed avi in it it is upside down and cant be corrected by opengl filter rotate . Even in latest night builds. But DV files works well...

In what way? Slightly brighter/darker overall? Slightly different reds and greens? Completely wrong colors? Upload some screen caps.

Some AVI files store the video right side up, some upside down. Use the Vertical Flip filter in avidemux if the video is upside down.

Try edit - preference - display and here try to change if it helps. Best is opengl in both menus. But maybe other will work for you better.

i tried it not working

I'm going to guess that the video is mod 2 and the decoder isn't decompressing it right. In that case you'll need to use another codec to decompress it. Can you post a MediaInfo report of the video? Is the whole video like that or just the first few frames?

This is not the same as the screenshot?

Is this a video game?
Is this being recorded with software/hardware designed for video game capture?

Can anything display it properly (VirtualDub, ffplay)? I tried once to save with "709" format (or something like that) and it was broken. Wild guess though.

It's uncompressed YUY2 video. Either the capture messed up or you have a playback problem. A capture device would have problems (dropped frames) writing data that quickly unless you're capturing to an SSD drive or RAID array. Can you upload a few frames? I opened a 1920x1080 24 fps YUY2 video here with an old version of AviDemux and it had no problems.

Why not just stick with Virtualdub?

[jagabo]

I didn't see any obvious way of duplicating the problem. I tried swapping U and V channels, inverting them, combinations of those but nothing gave the same colors. I'd dump AviDemux, it's full of bugs anyway, and use another editor.
