Different Frame Rates in CS5
I am working on a Premiere (CS5) project that includes a combination of the following formats – H.264 and AVCHD (.MTS files). I started the project under the SLR 24 fps frame rate. Unfortunately, the AVCHD footage was shot at 30 fps, so after I render the AVCHD footage (30 fps) looks choppy. Is there any way to fix this? I’ve put a ton of work into this already, so trying to not have to start over.

You want to be editing in a 30 fps sequence (29.94), not 24. 24 fps material will look fine when pulldown is (automatically) added in a 30 fps sequence, whereas 30 fps material will never look good in a 24 fps sequence (will look jumpy) due to frame/field decimation in the conversion, and less motion blur compared to material shot native 24 fps.
If you are having problems cutting and pasting (above post), try checking the “interpert footage” right-click menu (on clips in project window) to make sure your footage is being interperted at the proper frame rate.

It seems to be interpreting correctly (both at 29.97) – I can’t seem to find a fix for this. There are gaps/spots of black between many of the clips after cutting-and-pasting.

I think the 24 fps footage should be interperted as such. Otherwise it will play at 30 fps, which could account for your short clips.
