500d - audio, raw, video, fps

[KrisjanisP]

Hello!
I have been using ml for almost year and finally decided to test out nightly builds, audio monitoring and crazy fps override on eos 500d/t1i.
And I have got a question - is it possible to monitor real life audio with av cable and extra wires and headphones? I can only hear sound when playing back the video that is recorded.
And another one - have anyone got any luck increasing 1080p video's framerate to 24fps atleast?
And, excuse me, how is it possible to record RAW video with 500d?

Hopefully, this topic will be seen and continued.

P.S. I made topic subject because I saw no 500d topics here. Hopefully, I posted this thing in right place.
