In other words, the patent office did a bad job when making search of things prohibiting the patent (normally just browsing other patents of the same area, not VDR/DVB-mailing list snoop).

If you take the time to read the first claim of the granted patent, 
you'll probably agree with my (non-legal) opinion that the patent does 
not apply to VDR. I can't copy&paste it, but it says
"A method comprising receiving video and enhanced content information 
including at least one identifier of web content associated with the 
video information; ...."

The patent's about getting "web content associated with the video 
information" in addition to just the video recording, and using that. If 
VDR did something like get subtitles from the web, it would be affected.

There are some other independent claims as well, but they all talk about 
associated web content.
