**Crossposting to ivtv-devel** I am experiencing the same problems. We have similar setups, but my harddisks are fairly new and really not slow. I've crossposted to ivtv-devel because I think the issue is related to the ivtv driver. Mythfrontend outputs 'prebuffering pause' whenever the video stutters. As you say, this only happens when I change channel, and is cured by pausing a couple of seconds. >From my browsing in the ivtv posts, I get the idea this has something to do with vbi code (given when this error started occuring) and what people are talking about generally ;) Is there anything that people who really arent looking to use CC/TXT can do to the driver to make this error go away? I perhaps have the wrong idea here... feel free to let me know if I have ;) Regardless... Any suggestions would be welcome. /drdaz ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
