Hello,

i face strange behavior with TV channels zapping when windows wakes up after a S3 suspend.
Indeed, PC wakes up, i start MP, i go to a TV channel (channel 1), everything is ok but:
when i zap to channel 2, it's the beginning of channel 1 which is displayed.
I must reboot PC to recover a normal behavior.
I guess it's a timeshifting issue.

Any idea?

Thanks,
Fabien

ps: i tried to kill TVService process but no success
