I have just joined the ranks of those who receive HDTV/DTV. I'm seeing a strange problem on 4-1, details a couple paragraphs down. Had I known/realized that the relevant standalone tuners were willing to output 480i signals I would have done this long ago, as my analog vhf reception leaves something to be desired. My house seems to be located in some sort of dead zone.
Anyway, I just picked up the Samsung T451, and after some initial panic with it not finding anything (although it paused longer than normal on 36, 38, etc) I was able to cure it by rotating the antenna somewhat (I hadn't yet corrected it since the last major windstorm twisted it) (an RS outdoor VU-something or other i've had for years). Unfortunately on FOX (28?) it finds absolutely nothing, and doesn't even pause as if its trying. Apparently fox is very hit'n'miss as there seem to be people north of me receiving it, and people south of me who aren't (i'm in Ogden). When I manually go to 28, I don't even get one signal bar. On kbyu i'm getting 6 signal bars and #7 flickers on occasionally. (and #6 flickers off occasionally). Antennaweb seems to think kstu doesn't even exist digitally, and at the moment I'd agree with them 8)
However, whats most concerning me at the moment: on KTVX (abc) 4-1 there is a line of pixels, maybe 10-20 or so pixels wide near the top of the picture and slightly to the right of center which are blinking to black approximately 3 times per second. This seems to be happening only on 4-1. It is not there on 4-2 or any other channel. Its there all the time. Is anyone else seeing this? Since its only 4-1, I tend to not think its anything wrong with the receiver, but on the other hand, I haven't found anyone else mentioning it, and perhaps 4-1 is unique from all the other channels somehow, causing the receiver to only exhibit this problem here.
Also, on 11-1 KBYU (pbs) the N in "casting" and the R in "org" blink about once a second.
Are these "normal" (being transmitted this way) or do I have a defective receiver I should try to exchange? (its less than a week from the store).
And does anyone know if its possible to directly tune to the subchannels (either with its remote or a programmable remote), or is one stuck with things like "enter channel number, hit channel up 4 times"? (which is a further annoyance because one must wait until its tuned in the current channel before you can hit channel up/down again, *and* it won't let you "watch" anything in the guide for which there is "no data" as the program info)
I have the receiver in 480i mode connected only via its s-video jack at the moment so I don't know if these problems are showing up on the other outputs or other output modes yet.
