[mythtv][Experimental PATCH] BIG DVB PATCH V1

Tue Nov 2 18:28:13 UTC 2004

Hello all,

I tried the patch on a SUSE 9.1 installation with kernel 2.6.8, qt 3.3.3 and 
a single NOVA-s card.
Great work!! Thats the way, things should work for dvb users :) But 
unfortunately in this early step
its not usable for me.

The first problem I notice, is that the initial scan process hangs at the 
middle of the progress bar,
without an error output in the terminal window. It simply sleeps :-) No 
problem for me, because
my most important channels are found. The main problem is, that the backend 
segfaults after
a successful tuning to a channel.
There were several warnings during compilation, maybe this is a useful hint 
to the developers.
I added the warnings from compilation of libmythtv and a gdb debug 
stacktrace from mythbackend
below.
