However it does decode from the vbi, and seemingly also the pdc tags, so the code could definatly prove reusable.

At first glance looks usefull as a alternative to tvgrab for creating xmltv listings with PDC info.
A first step?
We have these current program pages in Denmark also, however its my experience that they also aren't quiet up to sync.. often 5-10mins. off..
Just tried with my bttv card using v4l2 drivers in kernel 2.6.8, and its fully capable of accessing teletext(/dev/vbi) and video (dev/video) simultanious. However, changing channel changes for both devices of course.
The PDC Signal is available for all bbc stations, rtl and most other german, and serveral other european broadcasts. its embedded as a special teletext frame, and can be read as such. much easier than decoding an entire page and parsing it :)

reading this also pointed out at teletext, a solution for the netherlands could handle:
Teletekest ned1,2,3 page 222/1 displays current program Rtl 4,rtl5, Yorin page 210/1 displays current program net 5,fox kids,SBS6 page 292/1 displays current program
Germany: Prosieben page 333 displays current program die "RTL"'s also have a simular page! (i just couldn't select it on internet)
UK BBC?
A capturing card capable of teletext can simultanioous look at teletekst while recording thus determin wheter a show is ended or not .............

I tried this, but my xmltv resource (www.tv2.dk) does not update timing due to late shows etc. I figured the recording server could be modified to look for pdc codes on a channel which its about to record on, if pdc is present, find the tag for the show to record (this is just a combination of the starting time iirc), and wait for the pdc go-code. When recording, simply look to the pdc code to change. A stop code is included in the pdc standard, but seemingly most channels just transmits a new start code...
There's a very exhaustive explanation of PDC here: http://625.uk.com/pdc/
This may of course have some impact on live-tv prior to recording, which of-course might limit the use of PDC. Personally however, I use Freevo mostly for recording and watching recording, and my ordinary tv for viewing actual live-tv. (Basicly a harddisk-based vcr.. )
I also have a few ideas for implementing time-shifting, since apparently, this is not yet done ?

I do agree with this.
I forced update of my program listings every 6 hours, not only for program delays, but because program changes the day itself are very common.
A already presetted record would not change to the new program times. When the program time changes, the old presetted record time remains in place. Perhaps this is also a feature to add.
