I just got a 533 from walmart. DVD playback looks great and it is surprisingly quiet. Unfortunately, I cannot tune some of the channels I bought this for. I think I've have followed what people have said to do here at avs to the best of my ability, but I can only get certain channels from my cable feed.
I'm in San Francisco where we have Comcast-Xfinity cable. I only get the basic service with out a separate digital tuner box. My Samsung UN40EH5000 can tune nearly all the local and basic digital channels for the local major stations and lesser ones. The 533 can only see some of them and often the digital channels are different from what my TV sees. Even more strange is that the 533 sees some channels that my Samsung CANNOT! Example: my Samsung sees WGN on "35-99" (1080) but the 533 sees it on "35.1". Our main local PBS channel (KQED 9.1) does not show, but 3 of the minor channels do. The 4th minor channel ended up way over at 54.1 where it shows as 9-2 on my Samsung. Interestingly, this channel USED to be separate at 54 analog before they merged with KQED.
I have connected my cable feed directly to the back. The wire comes out of the wall and goes into the 533. I have set the 533 to use digital tuning and tried all sorts of settings. I can manually tune some of the major digital channels for the big networks, and it will stick (like 2.1) but I just see a black screen with no sound. At first I thought the 533 might not "see" any hi-def channels above 480, but have found some that are 1080 and the recorder drops them down.
I know that Comcast has made some changes in the area over the summer, but I can still see the digital channels on my Samsung, even 1080 ones. I feel like I have tried every setting. Am I missing something? What is different in the tuners between the Magnavox 533 and my Samsung? Any ideas?
