So I'm still wondering if anyhow one can use demux_ts with DVB-input to achieve transcoding in the way I discribed above? So that I end up with an mpeg4-file without re-encoding.
as I wrote, re-encoding/transcoding - however you call it - is still done 100% by your cpu: there's nothing done by the dvb card, not even the mpeg2 decoding (although it's possible to make the dvb card to the actual decoding and use mencoder to read the uncompressed audio and video streams from the card's output: tv://, but I would never bet on the synchrony)
a small correction here: when playing non-mpeg2 content the transcoding to mpeg2 is done entirely by the cpu, so probably your source is already in mpeg4 and you don't need to access tv:// to encode it; in any case if you want an mpeg4 output you have to transcode your source using mencoder (the decoding process done by the dvb card is still possible as I described) -- "Without a frontend, mplayer is useless" - someone in mplayer-users
