    So I just got an external LG dvd player and it takes forever to burn a dvd, like 3-4 hours.

    I use DVD shrink to get it less than 4.7 gigs, then it takes forever to encode and then copy.

    I am using Nero, and my system is a P4 1.3, 640 ram. Its connected through my USB port and mine is only 1.1, not 2.0.

    I realize my system is old and slow, but it just doesnt seem like it should take that long. Once it does finish burning, my backups are perfect, it just takes too damn long. Anyone know what I might be missing, or if there is something I can do to speed it u?

    Thanks

    USB 1.1 is 12Mbps *maximum* theoretical throughput. In reality, it's even less.

    4.7GB = 4,812.8MB = 38,502.4 Mb

    38,502.4Mb / 12Mb/s = 38,502.4Mb / (12Mb/1s) = 38,502.4Mb * (1s/12Mb) = (38,502.4Mb * 1s)/12Mb = 38,502s / 12 = 3208.5333s = 53.47555m

    So even at MAXIMUM speed, you're taking at LEAST 54 minutes... And that's straight data transfer. You arn't accounting for all the other crap that goes on in burning a DVD. (Lead-in, Lead-out, finalize, error-correction, etc).

    At a more realistic 6Mbps you get:

    106.95111m = 1.7825 hours just for the transfer


    And your computer sucks -- it just wasn't designed to burn DVDs at high speed. If you moved it internal, it would be better.

    sorry, I am using an LG GSA-2166D. It says max write is 4x for DVD-R DL and 8X for DVD+R DL. The discs are FujiFilm DVD-R. So it seems I can only burn at 4x using these disks, but it still seems much too slow. It is 16X for DVD-+R.

    It mentions on the box that I should flash the firmware to get the 4X and 8X as mentiond above. How do I tell which version of firmware i have?

    Thanks

    You'll NEVER get close to those speeds on USB 1.1

    Well that makes sense. Atleast I know what the problem is. Also, my dvd burner plays all dvd formats, so which is the best format to use: +, -, -+. I am not concerned with RW. Just want compatibility. Thanks for your help.

    FYI - I didnt buy this burner or media, I am just trying to make it work.

    DVD-R has the best compatibility. I prefer it for normal movies. But DVD+R has additional features for pics, etc. Depends what you're doing.

    I've always burned using DVD+Rs and have never had a problem with compatibility. I bought a stack of Sony 16x +Rs a couple weeks ago because they were on sale. Package said 1-16x, my burner is a LiteOn 8x, and they only burn at 2.4x. I usually use Memorex blanks, which even the 4x discs would burn at 8x, but the Sony discs were on sale. As Jolly explained, your system is bottlenecked to some extent, but the discs could cause issues as well.

    Using DVD Shrink, Memorex discs, beginning to end is usually around 50-65 minutes. My computer is a P4 1.7 with 1GB PC133 ram.

    Following up on what Jolly said, go buy a USB 2.0 add-on card from Newegg or someplace like that. Even if your old motherboard can't handle (real) USB 2.0 speeds, it will still go a lot faster than USB 1.1.

    Given the cost of USB 2.0 add-in cards these days, you may want to buy one for every computer you work with that doesn't have USB 2.0 built-in. It will make your life more pleasant.

    I did just that. Got one from newegg for 10 bucks. Hopefully it will speed this up somewhat. Does DVD shrink typically take a while as well when it is encoding? THis seems to be a lenghtly process as well, possible longer than the burn.

    The encoding process is much longer than the burning process.

    Yep. My dual Opteron 252 with Plextor 716A has burned
    a dvd from rip to burn in under 12 minutes.
    That was using dvd decrypter and dvdshrink.
    I believe both of those progs are mulit threaded.
