I also get my movies turned upside down, but only some of them.
Some are displayed correct.
Additionally, some of the videos are gets flipped when I try to view them
fullscreen. This goes for both the corrrect and the faulty movies.

On top of that, the only program that seem to handle all this correctly is
WMP 9.
As long as I use WMP 9 everything works, but I wan't to use my Winamp 2.91
player.

Someone tell me what's up in my PC?

ps. prior to a HD-crash everything worked ok.
winamp 2.91 isn't the problem. not in itself anyway.
I've been advised from friends that the problem is that WA uses one set of
decoders while WMP uses another set.

How do I determine which player uses what set, and how do I correct it so
that WA uses the same set as WMP?
