    Got the discs today and ran on the CATS tester. They show a POF at the location indicated by the drop in your Eclipse performance analysis…

    POF = Parity Outer Fails – The decoder was unable to correct the data using the outer parity codes in the first pass. The wording “first pass” is important because the decoder may be designed to do several passes of error correction. There is a possiblity that the error may be corrected in following passes. This explains why your problem doesn’t show up on every drive.

    POF is measured over 1 ECC block and the highest possible value for this parameter is 1, which indicates a probable uncorrectable error.

    POF should never be present on a DVD!

    There are a few other parameters out also… Bottem Jitter, Radial Run Out, and DPD amplitude (related to the RRO) These aren’t real bad and shouldn’t be causing any problems – the problem you’ve had with these discs is caused by the POF.

    I just faxed a copy of the test summary.

    Best Regards, -Scott

    I have a similar problem to the above, I had someone author a dvd for me, the dvd was dvd9 so he exported it to (2) DLT and then burnt me a couple of copies of the film on dvd9r, the DLT’s were then sent to the replicator and the burnt discs sent to me, the burnt discs worked fine but when I took delivery of the manufactured discs they did not work properly, firstly one of the buttons on the main menu did not work, secondly at 1 hour 24 minutes into the film it goes pixilated and when it clears the film is about 2 minutes foward from where it should be (the counter on the player does not skip).
    I have been in discusion with the manufacturers and they were saying it was an authoring problem but I argued because the burnt discs work fine! They are currently running more tests but I feel they won’t want to admit to it being their fault, I came across this thread and tried copying the files from one of the manufactured discs to the HD on computer but get an error message error copying file….. file system error (-2147351799)maybe this is some sort of protection on the discs? the authorer says he didnt put any encryption on the discs!
