The only card that is even moderately close to the dstream design is the Hauppauge WinTV-D. This is the older HDTV card that only supports standard definition output. Hauppauge sells the card on their web site for right around $300.
A while back J&R was selling the WinTV-D for $50, but that was only for a short time and hasn't been done since. You can find some of these cards selling on E-Bay for about $150.
Of course, the card is only SD. In order to get HD playback you need a software DVD playback solution. No one has released software that can perform that trick using current hardware, but it's likely that if you had a Radeon and the video MPEG-2 decoding acceleration features were being used a PIII 1Ghz might just barely be fast enough.
