One of the local stations I can receive OTA has no sound, just a picture on my 622. My 2 CECB's get the channel with sound, including a DTV-PAL! I tried deleting and rescanning but still get no sound. I even got a replacement 622 (not because of this issue but because my internal hard drive was dying) and it still got no sound for this channel. It's not a big deal, this station is a LPTV station that converted to digital and they carry a national network 24/7 that is also on E*. Its probably a bug in the 622 software, seeing how both a DTV PAL (which is made by the same company as the 622) as well as a Zenith 901 gets the sound just fine. The station is: WCDN-LD ch 53.1 (rf ch 7), Cleveland, OH. I get a strong signal, I live 1 mile from the transmitter
