 Posted: Wed Jan 19, 2005 2:43 am Post subject: Parental Management Info |
 |
|
| When exporting, I notice the Parental Management Information has been cleared in both VIDEO_TS and VTS. Currently I have to use IfoEdit and HexEdit to add all those back in 5 different tables. It's very time consuming if you have many VTS and PGCs to edit. Would you leave them alone in the next version or so. Thanks. The reason is clear: you don't want little kids to watch movies, for example, that are rated PG-13, R, NC-17, banned, especially while you're away. How 'bout add it as an option under Tools->Options while those who want to clear or keep it. By the way, does anyone know how the value is being used in VMG_PTL_MAIT table of VIDEO_TS? I see on some dvd, e.g. on Level 8, the Parental mask is 2, sometimes 0x8000, 0xFF00. I don't know how it affects navigation. I know how the register is set based on these below: VMG PGC 11 1. R[0] = parental_level <-SPRM-13 2. R[0] &= 15 3. if (R[0] < 7) Link PGC 21 4. Link PGC 2 Suppose a movie is rated PG-13 - value 4.The value 7 on Line#3 suggests NC-17. This I don't understand, shouldn't it compare as R[0] < 4? As a test, I set it at Level 4 on WinDVD and on dvd player, and it displays the Parental screen, and stops playing. When I set it at Level 7 or 8, it plays normally. Last question, when you reach the Parental screen, it asks if you want to continue, if you select "yes" it executes the post-commands: 1. SetTmpPML 8, goto line 3 2. Link PGC 4 "cannot continue...eject the disc" message 3. Link PGC 2 FBI warning Even if I select "yes", it still jumps to PGC 4. Why? Doesn't line 1 mean to set it to Level 8, and jump to PGC 2? |

 I have to agree with toaddub, why not make it an option to keep the parental management stuff? | toaddub wrote: | | Last question, when you reach the Parental screen, it asks if you want to continue, if you select "yes" it executes the post-commands: 1.

SetTmpPML 8 means attempt to set a temporary parental level of 8 and if successful goto line 3, otherwise continue with the next statement. I think player behavior varies on this. The player is supposed to prompt the user for a password and if the correct password is entered, execute the command (goto line 3 in this case), otherwise execution should continue with the next statement. |

| I like it the way it is now myself personally and yes all my children are grown, but when the grand babies come to visit I have all my PG-13 and up rated movies locked away is a special place where the little ones want get a hold of them plus I don't have to keep a parental level set on my player. |

Thx, rubicat. That's what I thought. Just need to confirm. I guess the keyword is Tmp. true, that's why it's an option. Having the best of both worlds. Besides, you can't always be there when the kids come to visit. Also, they will adapt quickly. If they really want to see it, they will find a way.  |

Not sure what I did but half of my previous post was missing... | toaddub wrote: | | I know how the register is set based on these below: VMG PGC 11 1. R[0] = parental_level <-SPRM-13 2.

This is a Paramount disc, isn't it? I have seen this before too. It seems that their approach is: If any parental level is set on the player (other than NC-17), ask the user if they want to allow the movie to be viewed by setting the temporary level (which should cause the player to prompt for a password). This is a pretty stupid way of doing it if you ask me. It basically is ignoring the level that you have the player set at and reducing it to two levels, restricted and not restricted.  @Mr_Fixer I have kids, but my version of parental management is pretty much the same as yours--lock and key. But I don't see a problem with having an option to keep the parental management stuff or not. That way you can keep it the way it is, and someone like toaddub can leave it intact and everyone is happy. |

No, it is Universal. Actually this is very common in most discs I've seen so far. Does anyone know this answer? The Parental ID mask is also in all the VTS. | toaddub wrote: | | By the way, does anyone know how the value is being used in VMG_PTL_MAIT table of VIDEO_TS?
