Hello
Pay dvb-t channels are broadcasted in France in H.264 (stupid choice imho), as some transponders on the satellite. Is vdr capable of decoding MPEG-4 AVC streams ? Will it be ?

VDR doesn't do any MPEG decoding itself. You need a *device* that does this (or a plugin that does it in software). However, so far there are no such devices with LinuxDVB driver support :-(

BTW: HDTV on German Channels (SAT.1 and Pro7) will be also in mpeg4 So, if you want to watch HTDV in future, a new DVB-S card supporting DVB2 and mpeg4 decoder is needed.
-> As far as I've used Xine, xine is able to decode mpeg4. Question still: how much CPU do you need for mpeg4 in 1900x1020?

My question was asked in a wrong manner. I meant a sort of plugin or vdr enhancement that could recode on the fly MPEG-4 streams into MPEG-1 so the device can decode it. For instance, the way mplayer plays H.264 Apple's trailers on a dxr3 card (well working and great picture)

Are those channels HDTV or SDTV? If they are HD, you would need a very fast processor to do what you describe. Personally, I'd rather switch the display to something better (a large CRT monitor, panel or projector) and enjoy the much improved image quality. Xine-plugin would be fine for this, but unfortunately libavcodec lacks support for interlaced H.264, so 1080i and 576i won't work (unless they actually happen to broadcast progressive 25 fps material, like movies). 720p50 should work fine if your CPU is up to the task.
There is currently no good VDR-based solution for your transcoding problem. You could use VDR only for recording and watch the shows with MPlayer. For HD video, finding a fast enough single-core processor (since MPlayer is not multi-threaded) for real-time HD H.264 to MPEG-1 transcoding could be difficult. Getting a new display is probably cheaper.
