FE keeps running audio...strange - Agreed, never seen that before
Pvr-150 pixelated - Right, they tend to be rock solid
Same channel when played back after recording looks fine? - Yes, it 
looks good
Note - just noticed this morning, something is wrong with scheduled 
recordings, playback was fine, but it had the wrong channel.  (sd 
instead of hd).

System setup:
Remote control and blasters:
-Usb connected mce ir receiver w/blaster outputs

Pvr-150:
-coax cable input from Pace dc50x digital adapter (video and audio together)
-uses channel change script with custom config file (script from MythTv 
wiki)
-script uses blaster transmitter #3 of mce box
-Pvr-150 has unused blaster output

Hd-Pvr:
-component video (r,g,b) & audio; all rca connections from Pace stb
-uses channel change script with custom config file (script from MythTv 
wiki)
-script uses blaster transmitter #1 of mce box
-Hd-Pvr has unused blaster output

Note -  Pvr-150 and Hd-Pvr use the same script; same file name, each 
with custom config file.  Should I duplicate the script and give them 
unique names?
(i.e. "LircChannelChanger-Pvr-150" and "LircChannelChanger-Hd-Pvr").

HD HomeRun:
-no script, just an Ethernet connection

Script setup is here:

This morning I notice that the jump forward/back are a bit sluggish.  
Last time I saw that, adding ram solved it.  I'll order another 2 gig.

See above, enough detail?

Yes, they provided the external Pace dc50x digital adapter, which is 
what started this thread.  I'll report back once the additional ram is 
installed.  Any other suggestions appreciated.  Thanks for the help.
