Samsung SIR-T351 ATSC (HD) Tuner
Too many factors to blame the unit.
I can agree AND disagree with everyone else's opinion of this unit. I have the unit connected to my 57&quot; Hitachi Ultrvision via DVI-D interface, and to my Panasonic receiver via TOSLINK optical. When I first got the unit I connected it THRU the receiver via Component (RGB) cable. I experienced video dropout during sudden bright scenes, and occasional audio drop out in Dolby 5.1 as others have. I should note I am 55mile north of Tampa Bay and get about 7 or 8 channels (plus sub-channels) with a roof top antenna (Channelmaster from about 1990). The video droppout was clipping due to the Receiver's shortcomings, once I by passed it the video was excellent all the time. I also have not had an audio issue in some time now. Granted, being a TiVo family we rarely get to watch alot of &quot;live&quot; TV, but it has been great. Bottom line is this: reception is key. The signal is digital and thus will be slow to decode, uncompress and prone to packet loss (equating to picture pixelization and loss of Dolby soundtrack) Remember the UHF days? Ghosts, snow, etc.? Same thing, only digital. I previously bought a Zenith unit and it only got 1 channel. The sensitivity of the Samsung is by far superior to anything else in my experience. If you want terrestrial TV in HD for FREE, you'll need to invest in a well tuned aerial. Also I have a standard vhf/uhf 35db booster inline, 30ft from the aerial and 60ft from the tuner and it does not interfere with the signal in a negative way. I give it 4 stars because a this point in time we are too close to next-gen receivers to expect this unit to live up to the expectations of each individual user.
