I have noticed this, as well. This started when I upgraded to mythtv-svn-8042 (fetched 11/26/05) from mythtv-svn-7283 (fetched 9/21/05). However, since the reason for the upgrade was improved DVB support in Mythtv, I also upgraded the kernel, and consequently IVTV from 0.3.9 to 0.4.0. I believe that this may ultimately be found to be an issue w/ the live-tv changes in MythTV, though I can't verify this because I made the mistake of changing more than one variable at once :( I ended up editing ivtv-queue.c and just commenting these error messages, as they occur at such a rate that it will eventually eat up hundreds of megabytes of disk space (/var/log/syslog, /var/log/kern.log, /var/log/messages) before syslog even gets a chance to compress the logs and eventually swap them out. For this reason, I would like to suggest that the error message be suppressed after it is printed once every 10 seconds or something. However, w/ 0.4.0 it seems that the ivtv driver will eventually enter a non-funtional state: the device /dev/video0 will cease to respond. For instance, "cat /dev/video0 > /tmp/test.mpg" will never write any data to the file, and cat will hang (evidentally, cat is stuck closing /dev/video0). Likewise, Mythtv will print timeout messages in its log file, and I won't get my shows ;( Hope this info helps!

I'm not completely sure the problem is IVTV's or |Mythtv's, but since the ivtv driver logs error messages at the time the |problem exists, I first try to see if someone on this list can help me |to debug/solve the problem. | |When I watch LiveTV and a planned recording starts, the ivtv driver |starts spewing the following message continuously and the recording goes |wrong completely. | |Dec 10 17:38:29 localhost kernel: ivtv0 warning: ENC Stream 0 OVERFLOW |#303: Stealing a Buffer, 512 currently allocated | |Restarting mythbackend (and then also the frontend) stops this and |allows me to watch TV again.
