    In single seat configuration, while there is a recording of a DVB-T radio programme in work, seeking a recorded TV program causes excessive disk activity.
    Once the disk activity starts it's very difficult to control MP as it becomes very sluggish to the point of unresponsive. If I'm lucky I can stop the playback of DVB TV at which point the disk access returns to normal and MP becomes responsive again.

    To reproduce this bug:

    Record a DVB-T TV programme
    Schedule a DVB-T radio programme
    When DVB-T radio programme starts begin playback of DVB-T TV show
    Seek +5 minutes

    I can't produce logs at the moment as the system is very busy. I also can't confirm which SVN build I'm on but it's pretty recent... one of the last couple of weeks. [Why isn't there a Help/About... for MP??!]



    For me this issue has been present since 1.0 RC1 baseline but I didn't use TV Server before that.

    If anyone else can confirm this as a problem I'll pull in some logs.

    Cheers
    Mark
