I seem to have stumbled across an issue with the time shift files not getting removed. I have my time shift files being written to a 1.5gb RAM drive. If I stop the live tv playback normally they get removed and everything is fine. However, I have two tuners and if I am watching live tv and then I have two stations set to record at the same time then live tv will stop playback so that the tuners can start recording but when that happens the time shift files from the live tv do not get removed. Then when I try to start live tv again it will eventually stop the playback because the ram drive is full. I have to shutdown MP and delete the files manually. This problem would probably only be evident if you are using a ram drive for time shifting but even if not it would still leave a large amount of unused files on the ts drive. I think either one of two things could be done to prevent this...1) Remove the time shift files no matter how the playback was stopped and 2) Delete the existing time shift files, if any, prior to creating new time shift files for a new channel.
