DVD Copying...

Post by **R00k** » Sat Sep 17, 2005 3:42 pm

I've finally been able to start backing up my DVDs using DVD Shrink and Nero. But it sucks knowing that they are being compressed to fit on the DVD+R's that I bought, which means there is some quality loss going on.

I don't understand - why is it not possible to buy DVD-9's so you can make lossless copies? Are they just super-expensive and hard to find?

No Idea but i would like to find out
Might have something to do with Duel layer DVD's as well?

Dual Layer DVD's aren't to hard to find locally around here and you get order them online easily. Cost is still high usually $2.50+ USD a disc because "they" don't want us to be able to make 1:1 copies on the cheap.

Stick with the Ridata (Ritek) brand I have a few hundred of these burnt with almost no costers. You will pay less for inferiuor brands but the coaster ratio goes way up especially when using a set-top player instead of a computer for playback.

8.5GB DVDs are close to $4.00 a piecs, which is better than the $27.00 they were 8 months ago.

Nice, I didn't realize dual-layer discs would hold the same amount as full-quality originals. It makes sense though. :icon14:

I made a copy of my Old School DVD last night, btw. I'm watching it on my DVD player this morning, and if there is any loss of quality, it isn't as obvious as I thought it would be.

When I made the copy the compression ratio was 58%, I think. Where is the quality loss the most obvious?

Dark screens with action, you may notice some large square pixelation.

Under 60% isn't good anymore. I always try to keep it 70%+ and get rid of useless audiotracks, interviews and such. or, if you like to keep the extras, set them manually down to lower quality -50%

noisy areas or shots with high action. i also use dvdshrink and it usually produces an excellent quality result which is almost indistinguishable from the original. Note that some newer DVD are setup to be anti-dvdshrink, but you can usually grab the vobs using dvddecrypter.

I do try to get the ratio to 65% by deleting some audio tracks or even remastering the DVD to get rid of undesirable additional video.

indeed. I often dont mind extra's.

you can usually get the compression above 70% by stripping out the alternative albanian/turkish/fijian soundtrack, the menus, and the anti-piracy short at the start
