Awesome! I'm really glad to hear that this is possible.
So, just to clarify, the following is what I now believe to be true.
Please confirm or deny:
1. HDTV shows can be watched on a standard definition TV, albeit at
far less than true HD quality
2. (#1) can be done without actually transcoding the recorded content
3. (#2) is true because the video card is scaling the content on-the-fly
4. If desired, the recorded HD show can be transcoded to a lower resolution.
5. If (#4) is done, playback of the transcoded show will require much
less processing power than playback of the original (non-transcoded)
I'm pretty sure that 1, 2, and 4 are correct. Not so sure about 3 and 5.
