Tool for Multiple Frame Rates to 24 fps

I've read through a bunch of posts here but have yet to find a solution for my specific trouble.

I am working in a cinema environment with a media player that will only handle 24 fps DCP formatted material. I have a tool to generate the DCP from pretty much any video source but the source must be 24fps to begin with. We receive media in a variety of formats including NTSC DVD, PAL DVD, 29.97 Bluray, 23.98 MP4, 25fps MP4, 30fps, etc. I've tried using Handbrake and Acrok media converters which work well if the frame rate is left the same as the source but as soon as it's changed, the video gets choppy, particularly with pan style scenes. I'm willing to use a paid solution if required but the primary concern is maintaining smooth video with sound sync all the while requiring as few steps as possible. Time is often of the essence and turn around needs to be quick.

Any suggestions are greatly appreciated.

tall order. you can't just ivtc because none of you sources were 24p to begin with.

you basically have 2 choices if you wish audio to remain in sync. re-sample or drop frames. the first causes ghosting as progressive frames are split to interlaced and re-joined to parts of other frames. the second will be jerky. for the first you need a video editor like vegas pro, for the second i'd use vidcoder as the results don't look too jerky and you can set up a preset you like and add videos to the queue easily and it will encode using all available cores.

Or AviSynth frame interpolation methods. For example, for the 30fps ones interpolate to 120fps and then remove 4 of every 5 frames to reach 24fps. For most 25fps sources, slow the video to 24fps and the audio to match. The same with 23.976fps - speed up both the video and audio for 24fps.

Or change media players.

Thanks guys for your suggestions. I'll run them up the flag pole and see what comes of it.
