I made a quick hack that implements an "EPG dump" every 10 minutes
into the file /video/epg.data, and also a small Perl script that reads
that file and produces HTML pages showing all the data.

The HTML conversion is very raw, no fancy layout, but it shows how to
parse the epg.data file, which stores the entire EPG data in a very 
simple, easily parseable format.

So, if you want to try that, get the file 

   http://www.cadsoft.de/people/kls/vdr/epgdump.tgz

and apply the two diff's to 'eit.c' and 'eit.h' (this assumes vdr version 0.68).
Then recompile 'vdr', restart it and wait 10 minutes.
After the file/video/epg.data has been generated, execute

   epg2html < /video/epg.data

This writes the HTML pages into the current directory.
Fire up your browser and load the 'index.htm' file.
After that it's plain Web browsing...

Have fun
Klaus
