Bits of info:
1. As I get these errors, they do seem to happen when a separate process
or recording has just ended a few seconds before.
2. Doesn't have anything to do with PVR-150 because I have a server with
no PVR-150 gettting the same errors.
Server config table:
kernel ivtv ivtv0 ivtv1
ivtv2 comments
Server 1: 2.6.20-1.2952 0.10.3_hacked* 150(LG) 500(philips)
500 Has the most errors and is the most full with recordings (one
almost every hour, back to back, simultaneous)
Server 2: 2.6.20-1.2952 0.10.3_hacked 500(Samsung) 500(Samsung)
none Has a lot of errors, records simultaneously, back to back, but
not every hour... just about 6 times a day
Server 3: 2.6.18-1.2798 0.10.3 150(LG) 500(philips)
500(philips) Very few errors (if any -- can't remember). Lots of simul
recordings, but only has a back-to-back once a day
I'm seeing "Couldn't find start of buffer within the first 256 bytes on
this server a lot"
Server 4: 2.6.17-1.2174 0.7.0 250 none
none Works perfectly.
Server 5: 2.6.18-1.2798 0.10.3 500(Philips) 500(Philips)
none Works perfectly.
Server 6: 2.6.18-1.2849 0.8.2 250 none
none Works perfectly.
Server 7: 2.6.18-1.2798 0.10.3 150 500(Philips)
500(Philips) Only records one show at a time on ivtv0, seems ok. However,
won't load ivtv1 and ivtv2 (see error below).
* With the change suggested by Hans in this thread
All kernels are FC6 except Server 4 which is FC5.
The pattern I'm seeing is, the busier the server with back-to-back and
simultaneous recordings, the more likely it is to have this issue.
To answer your question, the MPEG streams are valid. Occasionally there
is no audio, but I think that's an entirely different problem.
I'll turn on the debugging and let you know what I see.
