Samsung SIR-T451 High Definition Terrestrial Tuner
Not ready for market...
I was debating between the Humax hfa100 and the Samsung sir-t451, and initially decided on the latter because of brand name recognition and its QAM capability. I was disappointed. <br /> <br />Samsung apparently had shipped a product that is not ready for market. The universal remote doesn't work for two listed and  different brands of television. One is led to believe that its simply a compatibility problem. However, on the troubleshooting page of the manual it implicates a STB/TV button. No such button exists on the remote control. Hence, even if one can find a \\"compatible TV\\", one cannot use the power button on the remote for the TV. <br /> <br />Secondly, according to an illustration in the manual, one is led to believe that different channel types (air,std,irc,hrc) can be added to the favorite channels list. But again, this is not the case. One must choose a channel type (air,std,irc,hrc) before adding channels via scanning or manually. But as soon as you do this, all previously saved channels are erased. Thus, from a convenience viewpoint, you have to choose from over-the-air(OTA) channels or unencrypted digital cable channels, but not both. Unless, of course you are willing to scan 68 channels for OTA, or about 120 channels for cable everytime you want to switch channel types. The scanning takes about 5 minutes each time. <br /> <br />Finally, the electronic program guide (EPG) does not retrieve program listings during power up of the samsung tuner, but instead waits for your first use of the EPG after power up.  This 5 minute scan procedure repeats itself after each power up. <br /> <br />The picture and sound quality is excellent. <br /> <br />After returning the samsung sir-t451, I bought the humax hfa100. The latter works as advertised. Its an excellent product.
