An application that uses the LinuxDVB driver can access the
DVB devices via /dev/dvb/adapterN/* (N = 0, 1, ...). However,
when it wants to, for instance, capture the current image on
a device (like VDR with its GRAB command), it needs to access
/dev/videoK, where 'K' is a number that is not directly related
to the 'N' mentioned above for the DVB device.
So VDR has to do some guessing on which /dev/videoK device might
belong to the /dev/dvb/adapterN device. This is getting particularly
problematic if there are also other /dev/video devices that have
nothing to do with any DVB devices.
Is there a defined way in which an application can query a DVB
device for its related /dev/video device?

Hello,
as more and more distributions are switching to udev, and udev automatically
creates device like /dev/dvb0.frontend0 and also /dev/dvb0.video0, switching
the applications to use these devices could simplify things alot.
I'm using a patched vdr which does this, and so I don't have to configure udev
or use any scripts.
Does this also solve the actual problem of finding the /dev/videoK (or
whatever udev calls that) device for a given DVB device?
