I am able to stream blu-ray files to PS3 from a Mac using MediaLink (awesome software).
Quick guide:
1. Rip to your hard drive using AnyDVD ofcourse.
2. Go into the stream folder of the ripped BD
3. Find the largest .m2ts file (that is your movie)
4. Use TSremux (a free program. Google it and download) and bring in the m2ts file found in step 3.
5. Pick the AVC or Mpeg2 file (check the checkbox)
6. Pick the Dolby Digital track (there will be several tracks here)
7. Click on button to run (should take no more than a few minutes)
8. Rename the .m2ts file to something meaningful like SpiderMan3.mpg <---------- Make sure it is mpg for PS3 to read it
Once renamed to .mpg, you can play this file using Windows Media player to see if the audio track you picked in step 6 is the
correct English. If not, go back to select a different track.
The whole process should take a few minutes (mine usually takes about 7 minutes per movie). You will end up with a file much less in size. The video quality is untouched, the file size is reduced because you only keep the movie and 1 audio, instead of the whole thing with several audio in different languages. Let me be clear here. The movie file is untouched and crystal clear 1080p, exactly the quality as the original.
Now you can use this file to stream to PS3 using (MediaLink for Mac or Windows Media Player 11 for PC folks). Again google "How to stream to PS3 using Windows Media Player 11" and you should find tons of guides out there.
Also, you can't copy this file to PS3 hard drive because PS3 hard drive is FAT32 and it has a file size limit. Anything bigger than 4Gigs, you are out of luck. Streaming is the only solution here. Make sure, you stream, using wire instead of wireless.
If all this is foreign to you or if you are a girl, then good luck
I can't help you.
