I have a problem. I want do make an .avi output from a dvd, but with 5.1 CHEANNEL AUDIO. Can you recommend me a software??
I made it with Flakmpeg, but there´s impossible to make an 5.1 channel audio. Or I´m wrong??
Easiest method I can think of is to use the latest version of Dr Divx. You can select to keep the original 5.1 audio in your final .avi file
well, thanks. I´ll try dr divx.
