hi,
but why should it be impossible to record the stream with a FF card?
what i forgot: if you use streamdev-server, you can do a "suspend live tv"; this disables the video decoding stuff and then it is possible to record and stream hdtv.
more infos about hdtv and vdr: http://www.vdr-wiki.de/wiki/index.php/HDTV (german only currently)
