I think I saw a posting about this problem a while ago but can't find it now.
When encoding avi files with TMPGEnc 2.52 I get a result where the picture appears to be seen through a purple filter, then changes to a green filter and then back to purple and so on all through the movie. This doesn't affect all movies I decode. I've tried switching to older versions of TMPGEnc but the problem is there too.
Anyone with a tip as to what causes this - and if it can be avoided? Or is it just the luck of the draw and something to do with the original avi files prior to encoding?
