    Hi,

    I just recently used DVDFab to backup one of my movies to dvd-9 and the quality was horrible, very pixelated, might as well just buy the dvd.

    I was curious as to how movies on bd-25 looks. There isn't as much compression of the movie on the 25gig disc and if it is like dvds then there shouldn't be much loss of quality.

    But I wanted to get everyone's opinion before I wasted money on bd-25 discs are they are still fairly expensive.

    Thanks,
    Dean

    I have seen some excellent BD rips at both 4gb and 8gb and not a single issue with pixelation. Not sure how they were done though as they were done by someone else. Also still in 1080 resolution. Perhaps look at alternative ripping/compression programs. However these will not play on a standard DVD player of course.

    After I started this thread last night I started a job with the same movie with BD Rebuilder, and yes I was pleasantly suprised, it took 16 hours but I am impressed with the results.

    I did select the highest quality which said it would be very slow.

    Does the default setting do a good job as well?

    Sorry, I am a newb to blu-ray backups, been backing up dvds before the time of shrink, I would assume the concepts are the same with bd backups but just want to cover my bases before I waste money.

    And is it worth buying bd-25 discs or are the dvd-9's using bd-rebuild just as good from a quality standpoint?

    thanks again
    Dean

    The default mode still comes out fairly good. It only takes 3 - 3 1/2 hours (on my PC). If you have the time do it at best quality, just let it run overnight. As for BD9 quality It depends on your display size. Also if you dont really have a good surround system, selecting "use 448kbps for AC3 encoding" can save room on the audio and allow more room for video quality. Every little bit helps.

    H264 is a very efficient codec and the quality even after extra compression is unbelievable, but you cant hope to get the same quality from BD9 as you will from BD25. The bits just aren't there. Also if you do have a high end surround system capable of 8 channel audio like DTS-HD-MA then it would be better to use BD25 and keep the high res audio.

    Verbatims DL are usually $40 at the store equaling $2/disc. I can get BD-25 discs at $3/disc. I would say yes. It is worth the extra dollar to be able to backup your movie with chapters and extras to a BD-25 to keep the HD Audio, allow for extra bits, and there is a high speed BD-25 setting which will compress and finish the movie in my rig in about 5 hours
