Right now, only with a lot of work and cross-compiling.
There are some DVB drivers and tools for WDTV around, but I don't think the drivers you need are there.
It's also a pain to get DVB working on WDTV and not really a noob task, sorry.
Next problem is playing DVB streams on WDTV if you get the dongle working.
I did manage to get two different dongles working on WDTV (Hauppauge WinTV Nova-TD and Sundtek MediaTV Pro) but it takes a long time (10-20 sec.) for the playback to start because DMAOSD seems to buffer a lot when you switch streams, it's not really usable. (Maybe we just didn't find the right way to start streams...)
