Here's a little podcast response for DIAMONDS OF KILIMANDJARO. The audio may be a bit of skipping and fuzziness, but I'm working on getting the bugs out.
[Edit] Might have to wait a bit for it to load. Will try to compress file better next time.
MP3 will give you a big reduction in size. I am currently using 128 kBits/s on a 44,100 Hz, 16 bit, stereo file and ten minutes of recording comes out to about 10 MB.
Oh boy, I have to disagree with you about "Oasis of the Zombies." Though I give both films a single slime, I've often considered dropping Oasis to a skull, while "Diamonds of Kilimandjaro" flirted with two slimes.
