Converting 29.97 footage to 23.97

Hello! I'm playing around with converting some footage I shot with my Canon XL1 at 29.97 and wanting to convert it to NTSC 23.97. I successfully did this in Cinema Tools, but now the audio is slow, which I expected. My thoughts are that it's impossible since I recorded video and audio on tape, when I should have recorded the audio in native 23.97 on a separate piece of hardware, or something. I poked around in Soundtrack Pro but didn't see anything.

I don't have an answer, but I'm dealing with converting 29.97 to 30fps, or vice versa. Reason being, I need to be able to use both cameras in multi clip editing. But multiclip won't function if the fps are different. On top of that problem, the footage from the two cameras gets out of sync on the timeline, probably because of the difference in fps--although maybe for another reason.
If you come up with anything would you let me know please?

If you use the Cinema Tools CONFORM option, then it will take every frame of that 30fps footage and make it play back at 23.98...slow motion. This is not how to "remove pulldown." You either shoot 24P that is designed for this pulldown removal, and then use the Cinema Tools REMOVE PULLDOWN option, or if it is just regular 29.97, then you need to use Compressor to convert to 23.98...making sure that your FRAME CONTROLS are all set to BEST.

Thanks Shane! I tried it in compressor and it worked, but only to find out that it increased the duration - making the video slower and audio pitch lower. Did I do it correctly? I'm testing this on a 30sec commercial, and while the 29.97 version was exactly 30secs the 23.98 version was several seconds longer. Sorry but I deleted it before writing this. :)
