If I record at 48 fps 720 and throw away every other frame do I get 24p?
apllies to HVX-200E?

I don't have HVX200 or 200E but, but i think that in the PAL version there is no 1/48 but 1/50. And you have only 25p and no 24p for sure.

Sure Does, you will be happy to know
scene file> frame rate >48

Moses,
The loss of sound will be the main problem with that technique. Please note that there is nothing magical about 24 vs 25p -- a 25p source is prefectly suitable for a film master. Before the was prosumer HD cams, many US filmmaker selected PAL equipment for indie film projects (for the 20% extra res) -- the 25Hz was not an issue. If you want to edit in 24p, you can use any of the CineForm (Aspect HD, Prospect HD etc.) products to rate convert 25 to 24 (or to 23.976) including audio resampling to preserve the pitch. This way you aquire in 25p and editing in 24p without any issues in post.
Note: If you are shooting at 25p on a 50Hz power grid, you won't have the lighting issues, i.e. beat fequencies between camera and the lights. European shooters a very lucky this way. Shoot 24p on 50Hz power has a nasty beat.

The answer is mainly no, but also yes-ish.
If you shot 48p with a 350-degree or 1/48 shutter, and threw away every other frame, then it would provide a pretty good approximation of 24p. However, it's not going to do exactly what you want, because as Milezee points out, the frame rate isn't exactly 48.000 (or, for that matter, 47.952, which is what you'd really want in order to have NTSC 24p compatibility). In the 200E, 48fps is actually 48.08, so on top of discarding every other frame you'd have to do a slight speed adjustment to get it to line up with 24.000 or 23.976. That would involve time-stretching your audio as well, although it'd be a very minor adjustment.
As for audio, you wouldn't have audio if you recorded in 25pN mode, but if you record in 720/50p mode at 48fps, you would have audio.

I can´t understand the reason to shoot 24p in Europe? If you get a distribution deal, then that company will do it for you, and 24p means you´ll have to convert the footage if it´s sent on television stations. 25p should take you all the way... And with digital cinemas popping up all around, 25p could actually be the only way to retain the quality all the way through (not having to convert back and forth all the time).
Just my opinion anyway.

By the way, I totally agree with Ursa here.
