LiveTV fails to change program info

[otto at kolsi dot fi]

I decided to try out whether latest fixes now allow long LiveTV sessions, so that it won't hang during program changes. I started LiveTV with one channel and let it play. After several program changes and several hours (5h) it still plays nicely.

Problem is that program information stops updating. Below is program info from the DB. I started the LiveTV around 08:00 and when reached to "Supisuomea" program (at 12:45) and checked current program info, it shows:

"Unknown (10:09 - 10:10)". Program length indicator shows something like: "2:50:00"

It has failed to update the program at that point and then this info stays although we are already going several programs ahead.

Program info:

mysql> select chanid, starttime, endtime, title from program where starttime > '2007-01-19 09:00' AND starttime < '2007-01-19 14:00' AND chanid = 1001;
