data446 You can use m2ts and MP-4 pass thru along with MKV.With MKV pass thru you can preserve chapter markers.If you don't need to change containers just leave the blu ray as full disk or main movie to save space.
Ozzie Do you know if the MP4 will preserve multi-tracks? I like to have my mp4 have the 5.1 as well as an AAC stereo for mobile play. I know MKV does but was not sure if mp4 did, I know a long time ago it did not.
