You are correct there is quite a variety. However my estimation was that DLP is winning in the market right now. Very few plasma are 1000 or above, as you know. However, the main point is, if you are not planning long term archival of your shows, transocding them down to the native resolution of your particular TV is wise. And even if your tv is 768 lines, 720 would still be a fine choice. The HD transcoding question gets even more complex because right now, most digital stations are transmitting their non-HD programs in their station's default resolution (1080i normally, 720p for fox/abc) Now this still looks a great deal better than recording analog or even the SDTV sub-channel many stations also broadcast. It's EDTV so I am not sure why it should be so _much_ better than the SDTV subchannels but it is. But of course it's huge, and with black bars on most. So your ideal world transcoder would handle these shows too, and crop (if 4:3) and downsize them to EDTV or some middle ground between EDTV and 720p. I guess the stations must have gotten complaints if they switched resolution on shows? Congress imagines that people will be buying DTV set top boxes to keep their old analog TVs working once the analog channels are shut down. These boxes will need to be able to do the crop etc. the way things are now.
