video playback upside-down

[SimonSez07]

i encoded my avs files using cce sp v2.66.01.07 and when i playback my m2v files in windows media player, it displays the video upside down (vertically mirrored). windows media player is using the following direct show filters for playback: microsoft mpeg-2 splitter v6.5.2600.2180 and cyberlink video/sp decoder v3.5.0.1011

any help is appreciated

[edit]
avisynth script looks like this:

SegmentedAVISource("tape-03.avi")
Trim(130,0)
ConvertToYUY2

You probably have a broken codec which decodes the avi file. Either fix that or use FlipVertical() in your script.

its actually now looking like the playback filters for the m2v files might be messed up, because the same m2v files played right-way-up on another computer. these filters are part of powerdvd which i will uninstall and reinstall to see if it fixes the problem.

but thanks for your suggestion boulder
