I have used other programs. 90% of the software I use is Open Source, and the 2 Virtual Dubs are no exception. Because people arent dropping money on them, they are developing their own expansions of the original program and making things better than the $1000 programs that other companies make you buy.
Open source is always the way to go when it is an option. I used to be a big software pirate in my younger days, and I try to stay away from that now.
