I found an issue with the view recording from beginning.

To reproduce:
1. Have multiple TV cards in htpc.
2. Start recording a currently playing show on channel A on card1.
3. Start timeshifting channel B (maybe only mapped to another card).
4. Go to TVguide and click the ongoing recording show (don't stop timeshifting).
5. Choose to view recording from start.
6. Notice that Timeshifting of channel B is not stopped.
7. Now try view channel A from TVguide.
8. In my case it sometimes crashes MP here. Sometimes it fails to start timeshifting on card2, but succeeds on card3.
