If warnings reflect different or wrong subheaders only (i cannot think of any other case right now) then we can have an additional note about warnings in database.

This disc has 4 errors in cdmage. There are lead-out sectors inside the data track. We should keep using cdmage because it's the only tool that gives sensible results. Non-data sectors inside a data track should be included in the error count.

Here are the last 4 "non-data" sectors: https://www52.zippyshare.com/v/pVD3oZwQ/file.html

I assumed they are lead-out sectors?

But subchannel of these sectors points data, not lead-out.
edcchk doesn't see the subchannel, so it can't recognize data or audio or lead-in/out correctly.

330553 sector is apparently a bad sector, bad edc/ecc.
330550, 330551 and 330552 are sectors edc/ecc is no problem.

iR0b0t wrote:CDmage does too much checks, different subheaders should not be flagged as an error.

edcchk cannot differentiate between data and audio sectors if you scan the whole image containing audio tracks, and if i remember correctly it treats empty data sectors as non-data, which would be incorrect, because it has to be an error.

I think so, too.

A problem is 16th byte (mode).

CDmage recognizes these 3 sectors as error data sector because 16th byte is not 0x01 or 0x02.
edccchk doesn't recognize these 3 sectors as data sector because 16th byte is not 0x01 or 0x02.
DIC recognizes these 3 sectors as non-error data sector because edc/ecc is no problem.

edccchk is clearly incorrect because these 3 sectors are data sector.

If incorrect 16th byte should be an error, CDmage is correct. If not so, DIC is correct.

It's easy to understand if 'error counts' of redump'org db counts only bad edc/ecc.

We should check CD specifications. If this byte is specified to be either 0x01 or 0x02 and nothing else then it should be treated as an error, otherwise maybe make it a warning.

How to understand the DVD-Video region from the logs? RegionManagementInformation: fd - what does it mean?

Posted: **Sun Sep 09, 2018 6:21 pm**

microsoft wrote:RegionManagementInformation

Indicates in which regions of the world the disc can be played. Each bit represents one of eight regions. If a bit is set, the disc cannot be played in the corresponding region. If a bit is not set, the disc can be played in the corresponding region.

I fixed it in 7/26.

e.g. dvd-video

Code: Select all

========== CopyrightInformation ==========
        CopyrightProtectionType: CSS/CPPM
    RegionManagementInformation: 2

e.g. xbox360

Code: Select all

========== CopyrightInformation ==========
        CopyrightProtectionType: No
    RegionManagementInformation: 1 2 3 4 5 6 8

Ecma-130 defines 0x00, 0x01 and 0x02. I knew 0x00 for the first time.

So, maybe you can adjust DIC with that?

If sector mode is not 0x00 or 0x01 or 0x02 then treat it as error. And in addition to that check mode 0x00 according to Ecma-130.
