  1. ive been doing dvd+r backups for about 2 years now. I first started with dvdXcopyXpress , but i switched cause i dont care for simplicity (only quality), I swiched over to using dvdDECRYPTER and dvdSHRINK(latest version) for my backups .
    i always backup my movies in 5.1CH quality audio.
    ive been reading that there are better ways to backup a DVD.(dont know what they are though)?..

    which way gives me the most quality?

    also , sometimes when i backup a DVD i get a option of AC3 or DTS????
    which audio is better ( FOR THE RECORD I HAVE A HOME THEATHER SYSTEM SO AUDIO QUALITY DOES COUNT)

    Hi towncarblue,

    You've much more experience than I at backing up DVDs. So I'll share only what I know and have heard - use it as a source for further investigation...

    1) If you don't do so already, tick "Perform Deep Analysis" (or words to that effect) in DVDShrink. This, supposedly, improves the quality.

    2) I believe that DTS is better than AC3, but I also think that you can't have it on it's own - that it requires another audio track to be present. I can't remember whether the format of the required audio track has to be WAV or AC3.

    Hope that helps some...

    Let google be your friend.

    The difference between the two are highly subjective. Only your ears, not others, will give you the answers on what's best. It's one thing to have a best audio system in the whole universe but if your hearing is not 100% up to par, then how can you enjoy your ultimate dream?

    You already have all the tools to test for Dolby and DTS in your household. It's all on the DVD. So, what's your verdict? One is better or you can't tell any significanct difference.

    DVD Rebuilder improves in quality by reencoding the images, rather than transcoding the mpeg-2 file. The difference - encoding looks at every frame on it's merits and encodes based on it's needs. Transcoding takes the existing compression and tries to squeeze it some more. Transcoding is much faster, but results are much more dependent on the original encode.

    Use DVD Decrypter to rip, use DVD Rebuilder to encode. Expect it to take 3 - 4 times as long as DVD Shrink with deep analysis and AEC turned on.

    I use Shrink is the compression is less than 90-95% (Shrink speak), and Rebuilder with CCE after that.

    As for DTS and AC35.1 - the biggest issue with having DTS on a single layer disk is space. If you keep only the DTS audio, you can't play the disk anywhere that doesn't have a decoder. If you keep both AC35.1 and DTS, then you loose up to 25% of your space to audio.

    Generally, I keep the AC35.1 for the backup, and if I feel the need for DTS, play the originals.

    DTS - This is from the Glossary - blue section, top-left of the page. It also answers my query (above) regarding having additional audio tracks present.

    Not sure about how to connect the DVD player up the best way... Sorry.

    If you make a DVD backup with only the DTS audio track, some players will not play it. Ac3 is a mandatory part of the DVD standard, all players must be able to handle it. DTS is optional. Even some players that handle DTS will not play a DTS ONLY disk, they expect an AC3 track too. Does this really matter if your player is happy with DTS only disks? Not at the moment, but sometime in the future you will replace your current player, and it may matter then.

    Actually, AC3 is only mandatory in the NTSC spec. Is it officially optional in the PAL spec, where LPCM and Mp2 are the mandatory audio types. That said. mp2 really only took off in Europe for a brief period, then AC3 became the defacto standard anyway.

    True.

    But the point is, DTS ONLY disks are not part of the standard. A standard disk must contain at least one audio track of LPCM, Ac3 or mp2 (depending on PAL/NTSC). DTS only is NOT part of the standard, so some players may refuse to play such a disk, even if they would ordinarily handle DTS audio.
