It is tight getting a 1 hour show to a single layer DVD-R, but you can often do it if you cut commercals. I seem to be able to get about 40 minutes per layer of the HD material that I record from my cable company.
Technically what I get over cable is 'HD Lite' because the bitrate rarely exceeds 12Mbps. Now, if the recording OTA, the bit rates are usually about 18MBps and it is much harder to fit it on a single layer. But it looks that much better.
Edit: I know it sounds lazy of me, but I've gotten very tired of cutting commercials, so I usually just dump the show to 2 DVD-RW disks. A half hour fits fine on one disk and FF past the commercials is really no big deal.
