ps3 wont play my avi?

[X400]

so, ive got a disc of avi files some over 2gbs (and if i remember a previous update allows avis larger than 2gb?) they're on a dual layer disc burnt at udf2.5

at first the ps3 showed everything on the disc as corrupted data, after trying to read the corrupted data it listed the names of all the files on the disc (battlestar galactica hdtv)

but when i try to play the files you can hear the ps3 trying to read the file, the screen will go black, the counter will come on, the speakers will hiss and than nothing

ive got no clue whats wrong with it :/ the disc was burnt perfectly using ImgBurn the files play if i try from my pc.. they're just simple avi files






another question what kind of subtitle files can the ps3 handle? .srt? and will it load those subtitles if the video file is a .mpg? (trying to see if converting the files into mpgs will get it to play)
