Is it possible for anyone to embed malicious code into a flash file or a movie?<

in a word yes<

Figures. 
So, allowing people to post those kinds of links and/or allowing people to upload those kind of files is skeptical if not dangerous. If the file is being uploaded to the server, is there anyway to check the file for these kinds of things?<

I think there is stuff you can do, but not entirely sure as I don't use flash.<

I don't use it either. My son works with it a little. I was not sure if I should allow flash uploads (or flash links [like with the video MOD]). Thanks Huw!<

Etymon, indeed people who want to do harm can use malformed flashfiles to do harm.
However, if you use the video mod that supports only those flashvideo providers who "prove" to be ok, there's not much that can go wrong. (My videomod only supports the big ones such as Youtube and Dailymotion).
If you support SWF files, via my other mod (the [flash][/flash] tags), you indeed may be subject to hackers embedding malicious SWF's.
But, then again, if you enable images you are also enabling them to do the same, except for the fact that the number of image-exploits is far more limited. The simplest exploit is this one if I'm not mistaking : embed a 10000x10000 pure white PNG (filesize is almost nothing) and the browser crashes as it tries to render it....<
