Can get correct video only on version <0.8.6i ?

[bolu]

Hi, I have a problem of playing UDP streaming (in "stream and media info" it shows stream 0:mpgv, Type: Video and stream 1: mpga, Type: Audio) with VLC media player after version 0.8.6i. Use default settings, I can get smooth video and audio with the version 0.8.6i, but I only get corrupt video (colors are all mixed and only chopped audio) on other versions after 0.8.6i(I've tried 0.9.0, 0.9.8a, 1.0.3, 1.1.4, 1.1.5).
So what has been changed since 0.8.6i? Is there a parameter in the config I can set to get the correct video with new versions? Thank you very much!
