I have dowloaded a film which plays back in The Playa and Windows Media Player with a very dark green hue covering the entire film. It also freezes a lot. I have reindexed the file and scanned for errors in Virtualdub and then made another copy of the file which plays back perfectly in Virtualdub but still has the dark green hue in The Playa and WMP (and still freezes). Converting to mpg results in a clean film which can be played back in both players but i would like to keep a backup in the original format. Can anyone suggest how to clear up the film so that it can be played back in The Playa and Windows Media or any of the other media players?
