[mythtvnz] Mythfrontend hangs hard when starting live tv

[Aaron Pelly]

Hi guys,

I've been lurking here for years, and you've helped with the odd 
question before. Thank you.

I've finally, after 6 or 7 years of good intentions, bitten the bullet 
and migrated from GBPVR to myth. I can not begin to tell you what a 
pleasure it is to have crossed this off my todo list. I'm a fairly 
experienced *nix user, no guru, but I get around no problems. Installing 
myth is no walk in the park. Anyway, after a solid day of installation 
and troubleshooting it works a treat. Another day experimenting and 
setting up preferences and recordings and I've completed the transition. 
Awesome.

Anyway, that's the background. Now, as you are aware, googling for myth 
info relies heavily on good google-fu. I thought I was blessed with 
this, but not on this topic it seems. Maybe my TV lexicon is misaligned 
with myth. That should resolve with experience, but in the meantime I 
have a few niggling questions. I will post each in its own thread for 
later searchability.

I have 2 hauppauge hvr 4000 dvb-s/s2/t cards in my backend (wtf?) I have 
only set up two devices; 2 x dvb-s. I have had trouble setting up the 
channels. I noticed that one of the discovered Prime channels seemed not 
to tune, and caused the frontend (on the server) to hang (error: could 
not read first 2048 megabytes) This required killing mythfrontend.real. 
Subsequent attempts to watch live TV caused the same issue, presumably 
as it attempts to start from the last channel watched. I'm guessing 
here. The backend doesn't seem to complain. Maybe I should adjust some 
timeout somewhere?

If anyone could shed some light on this, or has a relevant 
troubleshooting link handy, I would be grateful.

Thanks,
Aaron.
