Do you have any signal issues in the backend log for any part of the recording? It might be worth correlating with the segments that you're losing just to see if there's a link. Next time I lose part of a recording I'll do the same check, although since I upgraded to FC2 from FC1 it's not happened.

Got the same issue with pcHDTV using driver 1.6 and mythtv 0.17. I recorded a long show (3 hours) and the last few minutes were missing.

As far as I know the backend puts entries in the log when it can't tune a channel, and aborts the recording to boot. Unless it has stopped this diagnostic, this is not the problem here. There's nothing logged at all for the missing section, by and large. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

The recorting always abourts with no signal, but only on channel 11.1 -- my other channels still record fine. Runing dtvsignal shows the signal is present and had fine strength.
