When you are playing TV in fullscreen and put in a DVD and say Yes to the autoplay dialog you can get TV and DVD playing at the same time.

Seen on CVS from 24-4-2005

HW: PVR150mce
VMR9: ON for both TV and DVD (renderless)
Codecs: Happens with Intervideo and MP codecs also if not the same codecs are used in DVD and TV. Did not test more codecs.

To reproduce:
- Enable autoplay for DVD
- Start MP
- Goto My TV
- Turn OFF timeshifting if it is on
- Set TV to fullscreen
- Insert DVD
- Say Yes to the autoplay dialog
- Now TV and DVD are playing at the same time.
