I am experiencing the same issue with my Winfast card
I have a PAL analogue cable TV system in europe - no set top box - and don't 
know what a channel change script is but presume that I just let mythtv 
change channels in whatever is the normal way.

I compiled the source on a mandriva 2006 system, and had had no such problems 
with any previous version of mythtv.  I've pasted below the messages when I 
ran mythbackend - there is clearly a problem, but I don't know how to fix it.
