[vdr] Re: Bug, or just me?

Replying to myself, great :)

After sending the mail I hooked up a monitor to the dvr box, and saw a bunch 
of error messages from dvr, ringbuffer overflow etc, only got the last few 
lines, didn't have anything to write it down :/

Btw, this Gentoo distro uses gcc 3.2, there were some warnings about 
deprecated header formats, not sure if that would cause the problem.

It's only been a few days since I got DVB working, and already the HTV Cable 
company sent me a bunch of brochures convincing me how cool digitv (Finnish 
thing? DVB anyway :-) is and that I should really order a digibox (STB) from 
them. SPOOKY! :-)

Cheers,
Dennis

PS - VDR looks great on a regular tv. Most "tivo" projects (usually based on 
software codecs) start with skinnable OSD first (usually Aqua style :) but 
the dvr OSD is very clean and easy to use, very readable! Kudos!
