Samsung SIR-T351 ATSC (HD) Tuner
Junk...don't bother with this unit.
Apart from it's clumsy primitive user interface, this unit has two tragic flaws:<br />1 - The on screen displays (program guide, info screen, setup menus, channel display, etc.) do not work when using the DVI port when the resolution is set to 1080i!!  You're totally flying blind, with no visual way to set or confirm settings or channels. Samsung has confirmed that it is designed this way, but could offer no explanation why!  This reason alone is enough to stay away from this model.<br />2 - The Dolby Digital implementation doesn't work correctly. When using the optical or coaxial digital output, while set to Dolby Digital output, the audio drops out repeatedly and constantly.  It will usually work fine for a few minutes, then it starts cutting in and out.  Changing channels will clear it up for a few more minutes, but the problem quickly returns.  The only way to get functioning digital audio is to set it to PCM, but then of course you can't decode Dolby 5.1 broadcasts.  Samsung has confirmed this design flaw, but offers no solution.  <br />Check with [...] and you'll find countless pissed off Samsung owners. Go with a unit from Zenith, LG or Motorola, you'll be much happier.
