I have been having a strange problem of late that is very frustrating. When I watch live tv or recorded tv, my system is losing time, a lot of time, upwards of 2-3 mins per hour. Recording or anything else that myth does, does not seem to effect the time. I have another FC6X64 workstation with the same NTP config that never loses time.
<br><br>My setup: FC6x64 using ATRPMS for all packages. All packages current. NTP configured and working, except when watching tv or recordings. My firewall is setup to allow UDP 123 and does show connections from the myth box on 123.
<br><br>Sample of var/log/messages for NTP for last night... Notes, I restarted the daemon at 23:15 after watching live tv for a couple of hours, knowing I had upcoming recordings. Recordings started at 00:30 and ended at 01:30, and I watched those recordings between 05:50 and 06:21 (yes I noted the time). All output below are while watching live tv.
