Subject: [mythtv] Problem changing channels ..


Hi all,
  I just had a hard drive die on me yesterday (ugh, knew I should have 
backed up all that stuff, 8 years of various things all gone !!) so I'm 
rebuilding my system from scratch, sigh.

Anyway, I figured I might as well get the CVS of myth installed instead 
of 0.7 (which I had running previously), after three compiles of QT 
(first time I forgot to compile with threads, second I forgot to compile

with mysql, third time's a charm) I finally have it running under my 
normal user (I had 0.7 run under a "mythtv" user which started it's own 
X server on a virtual console and will do the same for this when 
everything works again), looks very nice too.  I have one teensy weensy 
problem though, it won't change channels, process is as follows..

 >killall -9 mythbackend
 >mythbackend &
 >mythfrontend

hit TV button
hit "Watch TV" button
live tv comes on screen, no problem, I can pause, rewind etc and the OSD

works correctly for those, if I hit "i" though I just get the OSD 
background - no program information
hit channel up, empty OSD comes up (as above) but channel doesn't change

(sounds like it tries, you know, pauses a 1/2 second), same thing for 
channel down
hit "m" to get guide, it comes up no problem, everything looks fine, 
program listings are correct, I move down to a program on a different 
channel and hit "m" again to "go to" that channel but it doesn't work, 
guide goes away but channel doesn't change

Can anybody give me a pointer in the right direction, that'd be great, 
it's just been one of those weeks.

Here is the settings table if it's helpful...
