[linux-dvb] dvb channel changing

[Geoff Leach <geoff.leach@bigpond.com>]

I'm using a Nova-t for dvb 2.6.1-mm1 with monolithic kernel (all dvb 
support compiled in). I'm using mplayer from cvs as of 12th Jan. 
Basically works great.

However I have a problem with channel changing with either the OSD or 
the 'h' and 'l' keys. With the OSD I can see my channels.conf is loaded 
and all my channels are listed. When I attempt to change channels I'm 
getting shared memory errors. The output below is from mplayer and from 
gdb.

[ws] Error in display.  15% 25%  2.0% 8 0 18%
[ws]  Error code: 172 ( BadShmSeg (invalid shared segment parameter) )
[ws]  Request code: 149
[ws]  Minor code: 2
[ws]  Modules: enable_cache

Program received signal SIGPIPE, Broken pipe.
