[mythtv] Frontend and backend hang after pressing F7

[Tino Keitel]

Hi folks,

with SVN 7457, the frontend hangs after pressing F7.

2005-10-12 20:29:39.279 AvFormatDecoder: Video has changed from 0x0 to 720x576.
2005-10-12 20:30:06.978 ReadStringList timeout (quick).

When I restart the frontend after this, the backend is broken:

2005-10-12 20:33:02.518 Connecting to backend server: 10.100.1.1:6543 (try 1 of 5)
2005-10-12 20:33:22.520 ReadStringList timeout (quick).

2005-10-12 20:33:22.531 ReadStringList: Bad socket
2005-10-12 20:33:22.531 Reconnection to backend server failed

Here are the last lines from the backend log:

2005-10-12 20:29:38.618 DVB#0 Rec: Found Payload Start for PID 439

After restarting the backend, live-TV works again. It would be nice if
all this worked without hangs or restarts.

I'm using an old WinTV Nova-T and Kernel 2.6.13.
