@westfw - I meant in terms of a submission for the PUSH N900 competition, running the TV output through an Arduino an N900 and making it do something different and cool.

As for modification of the playback, I'm not entirely sure, I think it can be, just have to rewrite an application to manage how it's displayed.
Could be a nice submission and put you in with a chance to win $10,000 an a trip to Vegas.
