    Hi,

    I've only just realised after backing up about ten dvd's that the video starts to get choppier and choppier about half way through nearly all of them. I was thinkin it had something to do with using the other two options for deep analysis and better encoding that was creating the problems. Its really bugging me as i've wasted days backin them up as my computers suck. One only 600mhz 64 ram, and the other is 1.2 celeron with 128 ram.
    Thanks for help in advance.

    Hi there billyd,

    You are indeed running on the edge with your PC's specs.

    In DVD Shrink go to edit, preferences, then for target size, set it to custom and type 4360MB. This will keep it from cramming to the edge of the disc -

    Also, we need to look at your media -

    Let's take Memorex as an excellent example as DVD media goes, 90% of Memorex is sub-standard as far as DVD backups are concerned, figures as high as 50% coasters have been reported (One member bought a stack of 50 and got 23 good burns.), not what I would call an impressive record. Memorex made a name for itself with their magnetic tapes (VHS and audio cassettes) and have been living off it ever since. There are 4 different companies that manufacture Memorex DVD's BTW and product quality varies widely as you might imagine. Only 10% of the Memorex out there, those discs manufactured by Mitsubishi in the 25 pack spindle are any good. It's easy to see now why the quality of a big-named company can’t be trusted - “ Who’s making your Memorex tonight ?”

    Is it just Memorex ? No ! I just used Memorex as an example, Princo, Orange Pack, Great AZO and most "store" discs aren’t all that suitable as a DVD backup media – that’s why we are specific in the type of media we are recommending.

    1. * Cheap media freezes, skips, pixelats and may refuse to be recognized by both burners and players :-( Besides "Freezing", "skips" many times you’ll get a “Cyclic Redundancy error” or an "I/O error". This message can mean that your discs are scratched or dirty, it can also mean that your burner won’t accept your “cheap” media :-(

    Another problem which, “Pops up” is a “*Power Calibration Error”. This can stop you right in your tracks and most often is caused by, Yep, you guessed it, inexpensive media. *A “Power Calibration Error” can also be attributed to the Optical Components of a DVD Writer, though this isn’t usually the case. Trying to shut down your software and ejecting your DVD then restarting your program and re-inserting the same media recently cleaned has been known to help in some cases.

    Orange Pack, Princo, Great AZO and 90% of Memorex plus many others are just not that good for DVD burning. Those same discs however, are quite good for your MP3 music, picture archives, Spread sheets and Data..Even DataSafe G04’s made by Ritek have been reported as an inferior quality media and are evoking that “Oh no, I shouldn’t have gotten those.”

    What we are suggesting is to download this DVD Identifier to find out who manufactured your DVD and if it's a decent quality.

    http://dvd.identifier.cdfreaks.com/

    Once you have your disc identified, click the "More information" icon and see what information you're given. if you're not sure of the quality, come on back and we'll check it out for you -

    2. A good grade, Hi-quality media is needed for DVD reproduction ! RiData, Sony, TDK, "Branded" Ritek G04's or "Branded" Verbatim Data Life, Verbatim DataLife plus, Taiyo Yuden's and generally, almost any discs manufactured by Mitsubishi are excellent bets. Among the better discs we're looking for, any media boasting "Advanced Metal AZO" - BUT it must say "METAL" AZO !, this indicates a superior dye and dye application on a good composite disc, while they are sometimes a bit "pricey" they are just the type of media we're looking for to do our DVD backups, Prices online from Meritline.com OR Newegg.com have gotten Ritek G04 starting at about a $ .45 (USD) a disc –

    For DVD backups, purchasing inexpensive media or even average media is a gamble, some people win BUT the majority lose, they lose varying amounts true but, they still lose :-(

    Using good grade media can guarantee you one thing to an absolute certainty; it surely cannot hurt.

    In an effort to clear the air, when I speak of "Cheap" or "Inexpensive" media, I'm not referring to the price you pay at the counter - I'm referring to poor quality control used during manufacturing and the quality of the dye, dye application or composite type used. I'm not saying it won't burn - Some may burn, some may not. It's quality is inconsistent, meaning it's not dependable.
    When I say "Branded" that means that when you pick up a disc in your hand, it says "Ritek" or "RiData" on the disc itself. The monetary cost of the media we recommend many times is cheaper than what you are purchasing now.

    We like to verify our information prior to recommending things. There are certain things we look at. For instance, when their dye and dye application are listed as unknown, this almost guarantees us they are using whatever they can get at a cheap price. Companies that use quality materials like to BRAG about it, naming names and staying with quality manufacturers who produce their media.

    Using DVD identifier and MediaMatch can help you find out a lot about what you're using. Purchasing your DVD media online can insure that you're getting quality merchandise at a good price. Shopping wisely will save you time, aggravation and money.

    Cheers, let me know how that works out -

    Pete

    Thx for your explanation, I was wondering why I always seem to get intermittent "witness protection" pixel noise on my DVD Shrink backups. I will as a result of your post, buy the media you have suggested.....thx again for the advice

    Your system specs are also very marginal for DVD burning - would strongly suggest looking at additional RAM - DVD ripping/encoding/burning are very demanding in terms of resources required.
