I have some classical music DVDs and I’d like to create a backup of these.
Of course, the best solution is create an ISO with ImgBurn and then burn the ISO on a DL disc, but I’d like to try an alternative, e.i. making an avi from the original discs.
I’m aware that the video quality of an avi is not the same of the original DVD, but the quality I can obtain with AutoGK is good enough for me.
The most important part in these DVDs for me is the audio.
For the most the DVDs contain both LPCM and DTS 5 channels audio. AutoGK allow me to create an avi with AC3 audio (see the advanced settings screenshot).
My question is about the audio part. I have no idea if the audio is changed in some way by autoGK. Can I assume that both LPCM and DTS audio will be identical to the original even if the video has not the same quality of the original DVD?
If not, there are better alternatives? I know that to improve slightly the video quality I can use H.264 codec instead of XviD, but again the audio part it the most important for me.
