Quick Time - an 1/0 error occurred

On my emac I have standard Quick Time 7.7 - not Quick Time Pro.

Just one or two of my VCDs play OK, the rest get this message;

THE MOVIE WON'T PLAY, AN 1/0 ERROR OCCURRED

How can I fix this?

Is there any other safe software I could use to play VCDs?

I googled the error message and one forum said download VLC player but I went to a site called VideoLan

http://www.videolan.org/vlc/download-macosx.html

and it said it's got a player for Mac OSX but I was nervous about downloading from a strange site so I didn't do that because when I hit

Download POWERPC MAC, it immediately got directed to another site called SourceForge

http://sourceforge.net/projects/vlc/files/1.1.12/macosx/vlc-1.1.12-powerpc.dmg/d ownload

so I aborted the download.

Why does my Quick Time play just a few VCDs and not the rest?

Is there any other safe player to download and try?

Thanks if you can help.
