You want to watch crap quality BB optimized videos on your TV?
I doubt it has been done. Afterall there is no video out connection on the phone now is there? If you have a PS3 then you could but you probably already have those videos streaming to your tv from your pc or laptop...

The headphone jack outputs AUDIO. There's NO video output.
Now, if you can access the Media Card and play the files with some other interface, that's a completely different thing. And will obviously work the same as other flash media sources.
