Not entirely, no. The analog broadcast contains only the standard definition version and only the primary channel for each of the stations. The digital subchannels aren't broadcast in analog. I'm in central New Jersey and Comcast sends me channels from both New York and Philadelphia. Each of the PBS stations are really three channels each, not counting the HD versions. Philadephia's PBS is WHYY, WHYY-Arts, and WHYY-Info, but only WHYY is broadcast on analog cable. > Transcoding the audio did indeed fix the problem.

It all depends on what your provider is sending to you. This can vary significantly by channel, time of day, phase of the moon, and the price of tea in China. Since the HDHR records whatever is sent verbatim, there's no guarantees about what to expect for bitrate or codec. > Odd.

No, I didn't spend too much time on it. I tried it a couple of times on different recordings and then gave up. > There are apparently no options to set resolution and bitrate settings for > HDHR recording profiles.

Right. None of the digital capture cards provide anything other than verbatim digital capture. If you want to transcode, you need to do it in software. That includes firewire capture as well as the PCI capture cards. The HD-PVR does have such settings, but that's not a digital capture device.
