Hi Guys, I compiled the latest SVN yesterday morning and ran through my Monday night mythTV recordings. 5 of them I believe. There was only one recording where the MPEG stream went noticably blocky, but it caught up much better than usual. Previously it would take 4-5 seconds to catch up and start streaming normally and we'd miss approximately 20 seconds of video. Last night it took about 3 seconds or less to catch up and we missed about 10 seconds of video or less.
This box only does recordings, no mysql, no mythfrontend. /var/log/messages: (the 22:00 was the one I noticed, I didn't watch the 23:00 recording) Feb 5 19:00:25 mythcorder kernel: ivtv1: All encoder MPEG stream buffers are full.
