Record HDTV from Your PC Over Firewire

I came across FireBus DTV Recorder (via Video Help) and it looks like a nice and simple way to record HDTV over your firewire port.

• Record MPEG-2 (HD & SD) content* from your DTV or DSTB to your PC over IEEE 1394 interface
• Record and play individual movies from the PC
• Self-configuring software identifies your PC as a storage device to the DTV.
• The PC can be configured to act as a Digital VCR or AVHDD upon startup.
• DTV recorder operates in the background and frees up the PC for simultaneous use. Less than 5% of the CPU is consumed when the PC is simultaneously recording and playing.
• Compressed video is captured from the DTV and stored to your PC. No need for expensive decoders or encoders on the PC.
• By using the DTV remote control, recorded movies (MPEG-2) on the PC can be played back to DTV with ability to stop, pause, fast-forward and fast rewind video on most DTVs with integrated tuners.
• Time Shift Viewing allows movies to be viewed from the beginning while recording is still in progress.
• Movies recorded on the PC can be burnt onto a DVD or CD.

Not sure about pricing but I think I saw a suggested price of $100. Seeing how all cable companies are required to provide a set-top box with firewire then this may not be a bad way to go.
