Shuffle - Random PGC's Ifo address

[catch]

Hi, I tried to send you a private message to the mail that appears on your web page and I couldn't:

'530 delivery not allowed to non-local recipient, try authenticating'

How can I send you the message?It has attached test files (4Kb).

The message is not an individual question, is about a correction of your web page "dvd information".

Thank you

Very strange, I'll check the mail server log later. You can send email to any of several addresses: majordomo@mpucoder.com, admin@mpucoder.com, or mpucoder@attbi.com

edit: I guess that would be AT&T (now comcast) mail server, not my own. They are going through some changes now to make a switchover June 30 to comcast.net (yes, another takeover, another name change), could be the cause of the problem.

Hello again

I tried the mails you wrote and always the same error so I decide to write the message here. You are an admin of this forum so you can delete it after you read it.


---ORIGINAL MESSAGE---

Hello, I am Jose from Spain. My english is not very good, sorry.

I have been training with Scenarist and the "shuffle and random" PGC's. After the project is done, I open the ifo file with ifoedit to see what bits change respect a "sequential" PGC.

The changes are in the table VTS_PGC_1 (my project is only one title) in the address 000000a2. If I change the still time of the pgc with scenarist and compile again, the change is now in address 000000a3.

In your web page (pgc.html), the type of PGC is in offset (address) 00A3, and the PGC still time on 00A2, if you compare with my results, they are exchanged.
I send you my test files, the name of the files tells you what kind of PGC I made.

If you are in contact with the creator of Ifoedit, let him know this (if I'm right, I think I am, but I am not sure) so he can make the changes to the program.

The meaning of the bits in your web page (pgc.html) are:
PG playback mode, 0=sequential, otherwise bit7 indicates random (0) or shuffle (1), and the program count is in bits6-0

As you will see in my test files, when I put in scenarist: program count=4, the bits 0-6 don't indicate 4, indicate 3.
If I put 128 the bits 0-6 indicate 127 and so on. So I think the bits 0 to 6 indicate the number of programs to play – 1 (the minimun number of programs to play in suffle or random pgcs in scenarist is 2 and the max. is 128).


Well, that's all. Hope I'm not wrong....


Good bye

Thank you very much for the research and report. I'll double check my sources to see where the mix up occured, but your evidence that the page is wrong is very convincing, and it will be changed.

Such a useful post I think deserves a change in the title so it can be easily spotted if ever needed.
