Its got 1 gig of ram, and is okay, I've had bad ram before, so know what to look for. I've even went so far as to put a gigabit nic card in the frontend and the backend, plus a gigabit switch between them, but it makes no difference. It has something to do with the ringbuffer, as if I tell Myth to record the program, and watch it from the recording folder as it grows, it plays back fine. I just realized my cache and recordings reside on different disks. I might investigate that to see if it is something. But it also sounds that .19 may fix this problem as it is going to treat livetv in a completely different way, at least thats what I gather. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
