Cannon Video (Mini DVD) & posting video

[GMMAT]

I habe to finalize/format each disc to be able to view them in the DVD player.  Even still, I have no way to view them on my computer (which will play DVD's).  When I get the help from MS....it says I need a decoder program.

I'm running XP....and the program's cheap enough ($9.95).  I'd like to know if this will take care of the issue.

If I can view the mini DVD....can I then save the video'd segments and send them to photobucket?  If I can get them to photobucket....I can surely figure out how to post them....right?.....lol

Thanks.
