</div></div>ok, logs and stuff.<br>
<br>
looks like my production box was last rebooted on Nov 23rd.<br>
<br>
--- from /var/log/dmesg ---<br>
ivtv: Start initialization, version 1.1.0<br>
<br>
no error messages in dmesg. and it looks like all three tuners were<br>
detected fine.<br>
<br>
looking at the messages log for Dec 15th at 8PM (when 'Chuck' and<br>
'NCIS' were being recorded) i see the following (over and over and<br>
over...):<br>
<br>
--- from /var/log/messages ---<br>
Dec 15 20:09:19 MythBox -- MARK --<br>
Dec 15 20:09:47 MythBox kernel: ivtv0: All encoder VBI stream buffers<br>
are full. Dropping data.<br>
Dec 15 20:09:48 MythBox kernel: ivtv0: Cause: the application is not<br>
reading fast enough.<br>
<br>
although, that says the application isn't reading fast enough, not writing...<br>
ivtv0 would be my PVR-250 which registers as card #0.</blockquote><div><br>I get this once in a while on my IVTV cards too. I *think* this is better in newer drivers (you might try upgrading them if you feel brave enough). A reboot fixes it. I set up a simple cron grep job to look for that in /var/log/messages and email me when it happens so I can reboot the system.</div>
