Sorry for the late answer, but buisiness is like hell these days.

Yes, i droped that just because of lazyness.
would be a derivation of vdrs list object overweightend or should i just 
take it?

Thats much to much memory waste for just two or three groups with around 50 
HasName entrys
So 64 should be a realistic limit for the meantime.
Who uses a rotor or a T90 _normally_ can read and write and adjust it

That's the ugliest pice of code at all
vdr doesn't return to it's main loop and watchdog is refreshed with a fixed 
value
The hole thing will change when i come to implement threading i think

Thank you, but it's to early for finetuning.
ATM autosort checks for each group wich channel could fit
That has to change to "where does this channel fit" with longtime goal to 
recive any kind of signal from vdr on channel change and resort this at once.
But first let me come to something that is allowed to be called "stable"

It is!

If I understood right, regex.h is the only thing i can expect to be 
installed on a minimal system (thanks to Darren for pointing me to that)
maybe libpcre can come later as addon, we'll see
