I think that TS and M2TS are just different extensions commonly used to package H.264 captured streams. It appears (from the program menu of TSRemux) that when you take the Dish R5000 H.264 captures with a TS extension and remux them to M2TS, the byte packets change from 188 to 192. If this is all that is needed for trouble free playback on a PS3, then I will consider purchasing a PS3.
I would also like to know whether it makes a difference for playback purposes if the original H.264 R5000 recording is compressed or at contant bit rate. IMO, compressed is much more desirable, because it is much smaller than the CBR files.
