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)
