My brother informs me that all - or at least the bulk of - commercial DVDs are VBR, and that by backing up with Clone DVD which is a CBR program, it maintains the VBR in the same proportions as before the shrinking process.
He also says that his DVD player displays the bitrate and that it shows his backed up DVDs made with Clone DVD to be VBR.
This would make a VBR program like DVD Shrink pointless in terms of the VBR and that I am needlessly allowing the analysis and overall process to take 1.5-2 hrs needlessly when I could just go back to Clone DVD.
It doesn’t sound right to me, I’d say that commercial DVDs would be CBR at the highest level bitrate. That said, CDs are VBR…
