[mythtv-users] Problem changing channels with cvs version of MythTV

[Anders Hanson]

I've checked some more things and turned all logging, done some code 
reading!

I think the problem that the 'no data' problem occurs when the CAM is 
unable to decrypt te channel
and reports a menu saying, 'no right', acording to the following log.

-------------------------------------
2004-03-18 23:35:34 DVB#0 Successfully tuned to channel 82.
2004-03-18 23:35:34 DVB#0 Adding pid 4386, type 0
2004-03-18 23:35:34 DVB#0 Adding pid 4130, type 1
2004-03-18 23:35:34 DVB#0 CAM - PMT cache updated.
2004-03-18 23:35:34 DVB#0 CAM - Sending PMT to slot 0.
Adding CA Descriptor (SID=0500)
CAM Menu Title: Viaccess Module
CAM Menu SubTitle:

2004-03-18 23:35:36 DVB#0 CAM - Sending PMT to slot 0.
Adding CA Descriptor (SID=0500)

CAM Menu SubTitle:

---------------------------------------

I think that the right thing to do is a retuning of the channel, on or 
two times before giving up.

Another separate issue i've noticed is that the frontend is blocked if 
the backend is unable to tune.
Why can't I  change channel or even stop the livetv when the backend is 
trying to tune the channel
