I did the upgrade; first the test box, then the production box. Test box 
upgrade went well, production box was a little weird, but I got through 
it OK (I think). Now the System Status/Listing Status reports 
"Mythfrontend version: fixes/0.27 (v0.27.3)".  Scheduled recordings are 
working well.  I still have the Live TV problem, but the failure mode is 
a little different.

channel playing normally - no audio on previous version).

Hitting escape has no effect.  Restarting X (rt-alt + prt-scn + k) 
restarts X normally, but the audio from the pvr-350 continues.  Log into 
X and MythTv starts normally (audio from pvr-350 is still playing).  
Trying Live TV (default is HD-PVR), it tunes the video properly, but 
gives me an audio error (Disabling Audio - Audio Player - Aborting 
configuration).  Hit escape to exit Live TV > hit escape again to exit 
MythTv > select "Yes, Exit and Reboot".

Rebooting was the only way I found that gets the audio back.  While 
writing this email, the pvr-350 seemed to timeout; audio stopped and 
Live TV on the HD-PVR works again (no error message and I  have audio).  
I had crossed through to the next half-hour boundary; looking at the 
clock, it's now 9:02am.  Any suggestions for the next step?


Note - Box has 2 gig of ram / video card has 1 gig of ram ...enough?
