What Version of iTiVo?
1.7.5
What Version of MacOS X?
Mac OS X Leopard (10.5.6)
What download format did you select?
Decrypt
What steps will reproduce the problem?
1. Download from TiVo HD
2. Attempt to play in QuickTime using (additionally purchased) MPEG-2 Playback Component
3. Hear no audio playback from QuickTime

I already realize this is a "known" issue -- the audio from the TiVo HD is AC3, which is not 
supported for playback in QuickTime.

However, when using Squared 5's MPEG Streamclip, you are able to hear the audio and also 
playback the video.

Is there a way add a process for audio conversion from AC3 to AC2 alongside the raw MPEG2 
download as an additional format?

I'm definitely not going to add it as a default format since it sounds very hack'ish
to me, but you *should* be able to achieve that by selecting the 'decrypt/copy'
format, and then changing the audio encoder flags (under advanced) to something like :

-srate 48000 -af lavcresample=48000 -oac lavc -lavcopts acodec=mp2:abitrate=192

(that's one line).  If you want you can even save it as your own format there.

  I assume you mean mp2 and not AC-2 (never heard of AC-2 myself).

  You will probably get a LOT of audio/video sync issues, but if that's what you're
trying to do.....  You may want to read up on mencoder to find out other things you
may want to do.  My personal opinion is :  If you're going to use the 'decrypt' 
format, do NOT use quicktime to view it.  It has TONS of issues.  Just use VLC
