Two questions...

What is the difference between DVD-R/+R? Which one should i use so that it can be played on a DVD player at home.

Also, does anyone have any good DVD creating software in which i can put a .avi file that i edited onto a DVD. I tried something called Super DVD creator 8.0... That didnt work cause the audio skipped on all the discs burnt. So if anyone has a program that they use, could they please tell me the name?

thanks,
bubbs
