I have a bunch of demos recorded in TF2 from before the Hatless update. Any attempt to open the files in TF2 for playback causes it to toss up a few resource loading errors that I'm assuming are the result of changes in the update, and the demo never loads.

Really all I want from these files is the voice chat audio, the action on screen wasn't important. Is there any tool available that can extract that information independent from TF2 itself?

On a similar note, for files that I can open, is there a way to make TF2 output just the audio track when recording playback using the startmovie command? I don't need the vast gigabytes of tga files.

While it is still in the experimental stages and only available in source code form (java), DemoReader by Asher Baker can decode and playback the voice chat audio from demos.
