The music wouldn't work for me on a WinXP machine, but it does on Win7. I did some checking and it's because of the sample rate of the WAV files. SoM's original WAVs were sampled at 22 kHz (705kbps), and the Moreatheia WAVs are in 44kHz (1411kbps). I think that high of a sample rate is over kill. I can't hear any sound quality difference and the 22khz versions are much smaller. To compare, even the highest sampling MP3 comes in at 320kbps.
Also, the intro movie doesn't play for me on WinXP or Win7. I expect it's just a codec issue. VirtualDub should be able to convert the videos to the Indio AVI format that the original SoM movies use.
PS. It's not really a bug, but I notice the word "alot" a lot. Usually, "a lot" is not properly written as a single word. Not to be confused with "allot" as in "I allot you $10 per day". However, I'm all for changing the norm if it makes sense, if that's what you're going for.
