MM2 CD unplayable on other computers. HELP

Several questions still unanswered after 3 days of searching/reading

1) Having successfully created movie (2 min) in different formats (I've
tried everything) I can write it to CD and it plays back fine with Windows
Media Player on my computer (both from CD and from the file I saved to hard
drive).
a) If I take CD to my other computer (also running XP and MM2), it plays
the music but not the video(just does one of those ambiance things that comes
with Media Player. I've tried differnt formats for saving, and am using
multi-media CDs (though not HiMat - couldn't find that). On anther computer,
it didn't even recognize that there was a CD in the drive.
What do I need to do to burn a CD that contains my movie (Video AND Music
together) that one can play on another computer?????
Should I give up and just go to DVD and if so, what software is best and do
I need hardware?

2) Tried saving to DV camcorder using firewire/ilink (used DV-AVI format).
Image playback is choppy with blank spaces. Do I need to give up and scrap
windows and just go to Apple for creating media like everyone else?

Thank You!!!!!!
