Avoid parental rating dialogs on some CAMs

[M-Reimer]

This change was originally made by @ciminus. As this VDR plugin is now "community maintained" (meaning there is no single person who actively maintains it) and, so far, I don't really understand what this change is for, I decided to put it into a Pull Request so this information is not lost and some discussion around it can happen here.

What I've found out, so far, is that this change may be related to parental rating dialogs popping up on the VDR server if a client requests such channels. This would mean someone has to walk to the server and somehow interact with this message. Good luck for a headless VDR server which probably displays this message into "nothing".

• Is this a change everyone wants to have or should this have a configuration switch in the plugin settings?
• What is this magic number "18" about? Where does it come from? Can this be placed to a constant or #define? I'm not a big fan of some unnamed magic numbers in code.
• Oh, and why is it no option to just go to the CAM configuration and disable parental rating there?

What is this magic number "18" about? Where does it come from? Can this be placed to a constant or #define? I'm not a big fan of some unnamed magic numbers in code.

This is the PID for the EIT Table (epg data) see table 1 on page 24 of https://dvb.org/wp-content/uploads/2022/11/A038r16_Specification-for-Service-Information-SI-in-DVB-Systems_Interim-draft_EN_300-468-v1-18-1_Apr-2023.pdf - 18 is 0x0012 in hexadecimal notation.

Oh, and why is it no option to just go to the CAM configuration and disable parental rating there?

I don't think this is possible on all CAMs.

That's a start to at least partially understand the change. Page 34 of your linked PDF says that everything from the EIT shall be transmitted in a PID with PID 0x0012 which is 18.

BUT wouldn't this completely block EPG transmission? This is by far too much. Just another reason why this PR should not be merged without more testing and optimization.
