It does. there is some preliminary support already for it in some of the 
more recent ck versions of the ivtv driver. If I have the util output 
all vps messages I got about 1 every 20 minutes orso, thats all testing 
I've done.

Now to get back on topic, how this would properly intergrate into myth 
is harder.

Making a recording stop when receiving the next vps is pretty 
straightforward. But when do you start? In order to receive vps's you 
need to be tuned into the channel. So you should already have a card 
listening for vps before the show starts. How much before? an hour? 3 
hours? a day?

I'm not that fermilier yet with the mythtv code, so I don't know how 
flexible it would be to a completely different way of timing when to 
start and stop recording. It would also be a pain to deal with 
conflicts. what if the show goes on longer than expected, moving into 
the timespace of another show that was supposed to be recorded.

what if you start listening for vps an hour early, but you were too 
late? you'll keep on waiting for the vps while you could be recording, 
only to find out at the next vps that the show is over..

So technically yes, the pvrx50's can receive vps's, but how to deal with 
them from a usability point of view is a whole other can o worms.

Looking forward to bright ideas people might have on this topic.

Bye, Lucas
