[mythtv-users] HDPRV Error -- ERROR no room on ep ring

[George Galt]

I've just started having trouble with my HDPVR.  Yes, I'm using
S/PDIF, but it hasn't been a problem until recently.  Below are small
sections of mythbackend.log and message.  There appears to be an error
in messages that I haven't seen discussed here before, and I'm
wondering if anyone has input on it.  FYI, googling didn't seem to
return anything of value.

message:

As you can see, the "ERROR no room on ep ring" message seems to line
up with the "MPEGRec(/dev/video0) Error: StartEncoding failed  eno:
Resource temporarily unavailable (11)" line in mythbackend.log

Anyone have any idea what these mean?
