What Video is sent to TV with Composite AV adapter?

Hi, hope this doesn't sound like an odd question, but exactly what is sent out to the TV with one of those Apple Composite AV adapters?

What I mean is, if I want to play video from the upcoming BBC iPlayer app, would that be sent out to the screen?

Likewise, if I just play video from a streaming website (I guess a non Flash one) would that also be sent out?

Do other third party apps work with this as well? I have AirVideo which streams from my Mac, would that be sent to the TV?

Finally, is there any way to control the iPhone from the sofa (pause/start etc) as I am guessing the Apple remote will not work.

What are the restrictions with this device?

Has anyone tested the composite out from the iPhone and can confirm if third party video apps work?

Third-party apps need to enable TV-out so it's on a per-app basis. You'd need to check the app store for each app.

Not tried AirVideo but StreamToMe (same idea - a server on your Mac and receiving app on your phone) works fine.

The iPlayer app on the iPad works fine with TV Out.

Thanks mrplow :O)
