does this even work(reliable) under windows?

I also think mplayer/xine/vlc/.. have a pva demuxer, that also might give you some infos.

you cant really speak of an 'OS'.
Basically, there is TDA10045H chip which performs all the DVB-T signal -> MPEG2-TS
conversion, connected to a TMX320AV7111GFN chip which is practically a full-featured
"set-top box"(TS Packet Parser+Demuxer, Video Decoder, ...) and a "usb chip" which lets
you talk to the first two chips via a usb stream.
The only thing which might be 'hackable' is the firmware which gets uploaded to the device
when it switches to PC mode.But as we have the firmware only as binary data, you would
have to spend a lot of time in reverse-engineering that thing.
