this is a combo patch that:

Browse Source 
1) adds an experimental TS demuxer to mplayer
2) adds an input (streaming) interface from DVB cards.
It compiles and runs with the following versions of the drivers:
dvb-kernel (HEAD) (with stock kernel 2.4.20) and 0.9.4 (with kernel 2.4.18)
patch by Nico <nsabbi@libero.it>
some cleanups, ts demuxer fixes by me

* Demultiplexer for MPEG2 Transport Streams.
*
* For the purposes of playing video, we make some assumptions about the
* kinds of TS we have to process. The most important simplification is to
* assume that the TS contains a single program (SPTS) because this then
* allows significant simplifications to be made in processing PATs.
/*
* WARNING: Quite a hack was required in order to get files by MultiDec played back correctly.
* If it breaks anything else, just comment out the "#define DEMUX_PVA_MULTIDEC_HACK" below
* and it will not be compiled in.
*
* Feedback is appreciated.
