this looks good for me(tm)!

I took a:
  * linux-2.6.8 kernel
  * video4linux-20040730-152601.tar.gz
  * dvb-kernel CVS snapshot from today (20040814)
  * and your patch.

First it did not work, but I figured that I needed to update and
recompile the dvb-apps. 

One problem remains: even after I compiled the current player 
(1.0pre5-3.3.3) against my new kernel "mplayer dbb://$CHANNEL" does
not work. 

->mplayer dvb://ZDF
MPlayer 1.0pre5-3.3.3 (C) 2000-2004 MPlayer Team

Playing dvb://ZDF.
code taken from dvbstream for mplayer v0.4pre1 - (C) Dave Chapman 2001
Released under the GPL.
Latest version available from http://www.linuxstb.org/
dvb_tune Freq: 562000000

... and it is stuck here. 

->./tzap -r ZDF -o - | mplayer -ao alsa -
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

This works. Probably the mplayer code needs some updates due to the
recent changes. I will try to investigate.

Thanks for the work!!
