Sorry for double-posting!
OK, I managed to find a codec for it here. The link is DIRECT, straight to the download. It is called codec 45, and the file is actually called sg726acm.cab. And for those of you that don't know, when you have finished downloading it, extract it and then right-click the .inf and select "Install". And there you go! But make sure that both the .inf file and .ACM files you just extracted are in the same directory, if not it will not work! :D
Now, just one more thing: I am looking for a converter, but I haven't been able to find a good free one. The Boilsoft one's trial isn't very good, because apart from the fact it is shareware and after the files have been converted they are HUGE, it also adds a bar across the bottom and some words in the middle of the video, so not very nice! WinMPG doesn't work well either, cause it also leave a message across the screen! Do you know of any which will not leave a message across the screen and at the same time is freeware? Thanks in advance,

P.S If there are any Apple Mac OS X users out there, do you know if Quicktime on them can play .ASF? Thanks.
