Channels.conf Line Generator - (DVB-S/S2)

Cool! I guess the RID is not a parameter that can be obtained by a channel scan or from kingosat. I would suggest to default the RID to 0 (zero). In most cases, users will never touch the RID

You could also add explanatory links to the sections regarding the different parameters listed here: http://www.vdr-wiki.de/wiki/index.php/Channels.conf
Sometimes the parameter names used in VDR can be misleading: In the case of NID there seems to be an "unsharpness" between ONID and NID that is explained here: http://www.vdr-wiki.de/wiki/index.php/NID

I think a HTML form like you provide is also quite educational for people who never took a close look at the syntax of the channels.conf strings. Thank you!

Further ideas around this topic:
1) A Greasemonkey script for Firefox that adds custom Javascript code to sites like kingofsat and converts the data of a line in a table of kingofsat into a channel string.
2) Programming this Greasemonkey script might be quite complex and it's maybe easier to program a scraper that will convert a kingosat page into a complete channel list.

But both ideas are not very educational - and that is one of the strengths of your approach!

EDIT: You could offer the satellite source as a dropdown box with all the official abbreviations of satellite positions in /var/lib/vdr/sources.conf.
EDIT2:
- The CAID is often not available in numerical form on pages like KingOfSat. But this is not such a big problem if the users know which parameters are mandatory for VDR to work with the channel and which parameters can be wrong and will be automatically overwritten by VDR: Example: If you don't know the CAID, just put in zero and VDR will fill in the correct CAID once it can tune the channel.
- User input should be sanitized (":" and ";" should not be allowed in input fields + XSS should not be possible)
