    Good day,

    About half way through my stack of 50 verbatim 16x DVD -R the dvd's i burn result in a nice set of coasters. PC wont recognise them as DVD's and my stand-alone player does play them with the occasional hick up but only till about 80%, then it freezes and i have to shut down the player.
    Tried to burn the same movie with That's dvd and allthough the standalone performs slightly better (completes the playback but with a hick up here and there)
    Checked the discs after burning with cdcheck and that gives about 4 crc errors on every disc, one in each vob file.
    Burned with another application gives same result as with Nero.
    Whether i burn 4x/8x/12x/16x doesnt make a difference either.

    Some specs:
    P4 3.0 HT, 1024 mb Ram, Xp sp2, NEC 3500 burner (latest fw), verbatim dvd-r 16x. nero burning rom 6.x.x.x
    DVD drive is set to dma2

    What i do is convert dvix/xvid to dvd and then burn. Something that worked fine for about 70/80 dvd's. The dvd files after converting are all fine, according to the analysis of dvdshrink and cdcheck.

    My best bet now (as that is the only part i cant doublecheck) is that the burner went more or less t*ts up.

    Any help would be appreciated.

    you're using good discs.... so I don't think that is your problem. You say you convert your files to dvd format, this might be a problem. What program are you using to convert. If it's Nero what version are you using? did you download the movie?? what movie(s) are you having this problem with?

    when converting files to DVD format I use VSO's ConvertXtoDVD! It's the best and never had problems with the files. Unless I downloaded the files and found them to be corrupted and it acted funny when burned!

    Thanks for the reply.

    Most of the dvd's i make are from converted, downloaded movies. If possible i go for the 1,37 gb versions, better quality.

    The prgrammes i sue to convert back to dvd wont even start the job if the files are corrupt so i gues sthe "originals" are ok. But i have tried with like 10 different divx/xvid fiels in the mean time anyway, cant believe there ware all bad.


    I mainly use 3 different programmes. But most of the times it is Nero Vision Express, 2x VBR (for quality reasons, allthough it takes 2x the time) or The filmmachine with cce eencoder (that takes agges but it is running on a, dedicated for this job, seperate pc).
    Doesnt matter with method i use, the same thing happens.
    As said (i think) if i test the video_ts folder before burning with cdcheck there is no problem. When the disc is burned there are most of the times 4 crc errors, one in each vob.

    Nero version i dont know by head, will have to come back to that later. But it is the same version i was using when everything was just fine.

    remember you are downloading files and converting them to disc! So with that in mind, what you download is what you get! Meaning that there could be something wrong with your files to begin with. And if it is the same movie try downloading a different file for the same movie! If it is ALL the movies you are doing now then there is something else that is going on here! And could very well be your drive! First I would try burning somethign that is not downloaded and test your drive out. Try playing something with that drive. If all works out fine then it's the downloaded files! good luck!

    Apart from indeed having tried about 8 different converted downloaded files i have not burned anything else. 2 others i tried where complete dvd's and gave me the same problem. If i remember well they were "dvdshrinked" though.

    If all goes well i should receive a dvd today i bought for someone else and make a back up of it and see how that turns out. Other than that i dont really know what to burn that i haven't downloaded.
    Playback function of the drive is ok, been forced to use the burner for playback since this weekend as i had to replace my motherboard with a new one that only had 1 IDE connection on board and that forced me to take out my dvd player as i had 3 IDE devices and you cant really do without a HD, can you :).

    Another thing ... i do smoke and have been thinking that could have effected the lens od the burner, any recommendation of a dvdburner lens cleaner?

    i smoke and it does effect the leds of the burner..the only way i was able to fix the problem,was take the burner apart and hand clean the lens.

    p/s i am not saying this is your problem,as they say where did the yellow go? its now on my sheep skin swabs..

    posted by a unknow poster i can not remember who.

    "There are three possible reasons for Cyclic Redundancy Check data error notification:
    1.) A defective disc, Only replacing the disc should help. Sometimes reading in a different drive works.
    2.) A copy protection with intentional errors (SONY Arccos, Puppetlock). Correcting AnyDVD settings (clicking "Default") or updating to the latest version often helps.
    3.) A dirty disc. Cleaning might help."

    Hehehe.
    Well i wish i had the willpower to quit, at €6,45 a pack i know it is bad ... for my bankaccount. And ffor the curtains too btw.

    But to get back at the original problem (shit, i do have 2 now.. smoking and the burner) I did take it apart and cleaned the lens with a q-tip and alcohol, but allthough i had 1 good dvd straight after that it got back to being bad again.
    1 week of no smoking and i ll have a brand new burner, that is not the point but just hate it when i replace something and it doesnt turn out to be the problem.
