That is what the Satellite locals and the distant west coast networks are for. In my area only Cbs is in true hd and dobly digital 5.1 sound. So every Cbs show is of course recorded over the ota station. The other shows I record on the locals or the distant networks I have on the West coast. The Cbs shows look great to me , especially the CSI shows . The other ota stations in my area look just a little better than their analog stations. The Satellite locals are okay for news, comedys and soaps.
But I agree the 942 would have been great if it had 2 ota tuners. Hell how about 4 ota tuners. Might as well shoot for the moon.
