i find there are some .rmvb format media file cannot be played with xine, and the error message goes like this:
xine engine failed to start.
No demuxer founder - stream format not recognized.
and the mplayer error message is:
demux_real: invalid chunksize! (-256)
cannot find stream file
what does that mean? is the file damaged, or is it only because of lacking of some kind of codecs?
