I wonder if that is due to errors in the streams? From Crystal Palace at least those channels are sent in QAM64 rather than QAM16 IIRC which is much more error prone. Possibly the transmission power for the multiplex is lower. Anyway the result is that I get a *lot* more errors on those channels, "five" in particular. Perhaps the mythtv protocol deals less gracefully with errors in the Mpeg stream? I would have thought it would just be pumping bytes, but maybe it is interpreting them somehow? You can check the error rates using tzap. I get just less than 0x1000 per second on five normally (which is the channel I use to see how well my aerial is working!) If you are getting more than that then you've got a problem. I have a different channel dependent problem... I can use the skip buttons to skip through C4, "five" programs and it works perfectly. However if I skip through BBC1/2 channels more than a few times then mvpmc locks up. > > Do you use -r /nfs/path/to/mythtv/recordings or use the filebrowser to > > play the recordings.

I have to say I've never tried the Mythtv protocol - I went straight to NFS with -r because I'm still running a much older version of MythTV (it ain't broke etc ;-) With -r, when I press OK I see a bar with time and progress through the program, recording time, program details etc. It doesn't come up unless I press OK though (not while fast forwarding). BTW I'm using the latest nightly build from ftp://buoy.com/pub/mvpmc/www.lison.com/mvpmc/ rather than the last release. -- Nick Craig-Wood <[EMAIL PROTECTED]> -- http://www.craig-wood.com/nick _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
