Of course you don't get commercial skipping or playback speed with  
live tv, but you can get it with your recordings. I don't ever cut out  
commercials from my recordings cause they are sometimes incorrect. I  
just want the video player to skip over them or notify me at each  
commercial break. You can't do that with the iPhone's built in video  
player.

At the beginning of my posts on this thread I mentioned that Orb Live  
already does exactly this using ffmpeg. I don't have their source  
code, and I haven't tried their product. I doubt they have modified  
ffmpeg for the iPhone since the iPhone is just another armv6 arch  
device, and to non-apple developers, without hw decoding support.

Like I previously stated, I already have video playback (though not  
yet audio) on the device using ffmpeg with reasonable quality.
