Hello,

I'm having problems using mythtv / PVR-250BTV to watch TV (and consequently
recording).
These are the excerpts from the log file:

2007-06-18 21:16:23.136 MainServer::HandleAnnounce Playback

Here's my configuration:
CPU: VIA EPIA EX15000G
Capture card: Hauppauge PVR-250BTV
OS: Ubuntu 7.04
MythTV version: 0.20 (installed using apt-get)

03:0f.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and
Audio Decoder (rev 05)
        Subsystem: Hauppauge computer works Inc. Hauppauge WinTV 28xxx
(Roslyn) models
        Flags: bus master, medium devsel, latency 32, IRQ 22

Running motv to watch live TV outside of mythtv as a normal user works fine
though.

Please help!

Thanks,
Shing
