You have to choose the output format you want in the menu, and the unit converts all output to that format. The choices for HD are 720p or 1080i. Try both to see which looks best on your HDTV.
2) You have to choose between PCM and DD for audio, right? If you choose DD, will it send whatever the broadcast is sending? Am I correct in thinking that not all stations send audio in DD?
No, all DTV stations use Dolby Digital audio, but it may not be full 5.1. DD audio can be anywhere from 1 to 6 channels, almost always either 2.0 or 5.1.
As already noted, the problem can be with the Dolby encoding hardware local stations use. If they get a 2.0 signal from the network and have the 5.1 flag set on the encoder, some audio processors (AV receiver, AV preamp, etc.) will only be able to deliver audio out of the 2 main left & right channels. When the DTVPal DVR is in PCM mode, it will allow the audio processor to use matrix decoding like ProLogic II or Circle Surround, for a simulated surround experence.
