Exactly, that's why I think channels.conf has to be XML-ized, at least
a minimum XML-ization to become a valid XML document.

XSLT is for XML the core engine that makes mirracles happen. XSLT enables any
XML to easily be transformed into any other XML format! XSLT is like a shell
running XSL scripts. The XSL script is actually a special form of XML
document, and of course, it can even transform itself!

It's built-in in mozilla 1.0.0 (and other browsers), everyone can experiment 
with it to generate e.g. valid XHTML pages. Web is full of small examples of 
XML_2=XSL(XML_1) coversion tutorials, couple of lines each. For me it wasn't too 
difficult to get familiar with XSLT

WOW, there's already a DTD :)!! Excellent findings, really

They have already features we cannot dream of with VDR, like the database
with geographic local exstraction possibility (though not too well
organized, but obviously functional). Plus they defined format to carry
the schedule of programmes, so application can automatically know when to 
start/stop recording things

I think that impressive features lead to sophisticated data format.
(and they are only dealing with plain TV, we yet have to face complexity of DVB!!) 

the good database structure is the key to get integrated media 
application do the simple-to-use record and watch
