Hi all...just replaced my 942 with a 622 HD DVR and connected my Winguard SS 1000 ota antenna to the CATV input. This is the only way I can receive local HD channels...worked fine with the 942...connected everything the same way...no ota signal at all...if i plug the ota coax directly into the HD Tv..I get channels, it is just not going thru the DVR 622. The Dvr is only connected to one TV in single mode [so i can use PIP] . The 942 was connected with diplexers..will not work on the 622...I ran a coax directly from the SS1000 to the CATV input on the 622...still no signal coming thru the 622...anyone else had problems????? Thanks
