Samsung SIR-T351 ATSC (HD) Tuner
Quite cool
I'd like to add some details about this tuner:<br />you can hook this tuner to a regular NTSC, non-HD TV and get TV pictures that is as good as DVD.  Also you can hook it up to a computer monitor too... of course, you need to hook up the audio to separate speakers that way.<br />i asked about six different stores about whether it can be hooked up to a regular non-HD TV.  Half of the stores said yes.  Half said no.  Some of them just said, no-no-no, you must hook it up to HDTV.  And I had to explain to them all I want is to watch the 5 channels of PBS in super sharp quality on a regular TV.  And they said it like they are reading from some education of HDTV material: no no no, you need to have an HD TV.  So I bought the tuner anyways, and sure enough, I don't need an HD TV to watch HD channels.  The picture is super sharp.  It blows me away.<br />only thing is... at night, I get a lot more channels, like 20 of them.  When it is near 7:20am, the channels would go away one by one...  I tried the Terk TV50 antenna as well as the Gemini ZHDTV1 antenna, and they are the same. [update: I found that the Sutro Tower in San Francisco has earthquake upgrade work going on Monday - Saturday 7am to 5:30pm, so that's why a lot of the signal is gone during that time]<br />also with this tuner, if I watch some channels which are in Letterbox format, then the top and bottom have a bar region that is gray... why isn't it all black?  if it is gray for a long time, it will burn the screen in.<br />it feels a bit slow to change channel.  it takes close to three seconds before any image is displayed.  also you can't choose channel 9-5 right away.  You need to change to 9-1 first and then press the channel up button four times.  If you add it to the Favorite Channels, then it helps.<br />the user manual feels like a \\"reference manual\\".  The beginner guide should be:  change the two switches at the back of the machine until you can see the on screen menu when you press menu on the remote.Then, don't worry about checking the signal strength.  Go straight to \\"Channels -> Memorize Channels\\" to scan all the channels to catch all the channels available.  Of course, hook up the antenna first.
