What is the best software to use to convert and burn avi files. I am currently using Convert X to DVD and DVD shrink which allows me to fit 2.5 hours worth on a 4.7gb DVD. Probaly could fit more, but I only usually put 2.5 hrs on each DVD. Sometimes the audio is out of sync, am I right to think its because Im trying to fit too much on 1 DVD? Is there better software out there to avoid the syncing problem? Any advice would be great!!!
