Just an update now TS, PES playback of mpeg audio, ac3, mpeg2 and h264 is working. Only 720p is stuttering, which is caused by a bug in vdr 1.7.16 index file generator, which is hopefully solved in 1.7.17, kls already published some patches.
I now have to add some necessary function for distribution, bootloader etc. . I will probably sometime in march go online with a repository for an open development.
Btw. my current code name is VDR on bluray disk aka VOBD, but I found out that this is already used by voice of bangladesh, so any ideas?
