I tried use DVD Burn plugin.

1) in some parts is pixelisation in created dvd. In .ts is all ok. Hmm... better will be make it on PC as always.

2) is not possible choose audio language for DVD. If there in .ts file are 3 audios, on DVD is only one and is not possible tell to DVD Burn, which is wanted ( options make nothing ). If was set all 3 audios, on DVD is only one too...

3) for future - could be displayed bitrate for audio channels in selection of audio (if is more audios with same language) ? It is better for orientation, which audio select.
(some provider broadcasting f.eg. 3 audios: 256kbits, 192kbits (only one channel ? - i dont know, for what it is) and AC3.
