Tvheadend

Hello,
First thanks for the TVHeadend project, you've done great work.
TVHeadend is almost perfect for me, excepted the scheduler. I would like to be able to create regular recordings who starts and ends exactly at a time specified.
For example a radio show who starts every friday at 22.00 and ends at 00.00.
It could be a similar scheduler than DVBViewer.

Thanks
