try wiki searches MKV is a Container and can hold multiple streams ( like a dvd ISO file ) Video ( X264 , H264 etc ) Audio ( ac3 , aac , vorbis , etc lots more ) chapter markers subtitles (srt , etc,) + more these programs in this order work very well for extracting into the MKV container converting...

The original disc is coded for english use as that is the first audio track on the list MakeMKV preserves the original information eg english 1 , german 2 to change this you need "MKVMerge Gui" in a pack called MKVToolnix 1. convert the file with all the streams you require with MakeMKV 2....

run it through handbrake on a high constant bitrate ,
you wont loose much quality and it will convert the video stream
to the h264 codec which will be identified on your ps3 .
( wont use too much processing power to do it )
