And what player will play TS? Maybe Xine and MPlayer as they support 
DVB-cards, but that's been it. The most available format is MPEG-PS, 
especially DVD/VOB-compliant one. This would allow to copy recordings 
directly to DVD or even record on DVD.

Ralph Metzler is working on a ts2ps-demuxer. I also mailed with Sascha 
Volkenandt about implementing MPEG-PS into streamdev-plugin. The best 
solution for VDR would be to take the cTS2PES-class, rename it to 
cTS2PS, add the necessary functions for the PS-headers and add it to 
VDR. So the cTS2PES-class could be used and plugins could try the 
cTS2PS-class. And when it is reliable, VDR could be switched to 
cTS2PS-class easily, as it would have the same interface like cTS2PES.
