dvbsnoop - no /dev/dvb ?

I'm used to using dvbsnoop on my Linux PCs. Just installed the opkg on my HDR-FOX T2, and noticed that there's no /dev/dvb on the Humax.

Anyone know what the device files are called on the Humax ? I'm guessing that there should be adaptor0 and adaptor1 (for the two tuners), but 'find' under /dev doesn't locate them.
The utility is packaged because it's useful for analysing recordings on disk. You can't capture the live stream on the Humax.
