Why does PMS try to transcode the video at more than the original rate..or is it something i am missing in my setup.
The easy answer is that your vob probably contains h264 codec (if its HD) and PMS transcodes to a PS3 supported format, mpeg2.
The fact is that you need higher bitrate in mpeg2 to achieve the same thing as with h264. h264 is much more efficient, keeping the high quality.
The problem with h264 is that not many CPUs can handle realtime transcoding of this codec, so mpeg2 is used, and hence the higher bitrate.
So the best thing is to play supported formats (pure streaming) or use tsMuxer for unsupported formats if not needing subtitle support. tsMuxer will only remux, so you will not get a higher bitrate but the original source bitrate.
For subtitles you will have to use transcoding.
