Samsung SIR-T451 High Definition Terrestrial Tuner
Adequate, but I like the Humax HFA100 better
Performance was disappointing after reading all the positive reviews. I purchased the T451 at Circuit City for $150. I live in line of sight of area's main transmission tower and have a good Channel Master outdoor antenna; so most channels come in at 90-100%. T451 picture quality was excellent at both 480p and 1080i settings. Unfortunately the T451 would reboot for no apparent reason. AC3 often wouldn't sync with video (sound-picture like old Kung Fu movies). Channel changing was excruciatingly slow. Electronic Program Guide (EPG) was nearly worthless. I returned it to CC after three weeks and was provided with a no hassle refund. <br />I replaced it with a Humax HFA100 that I bought at Frys for $206. Picture quality of the T451 seems slightly better. However, the HFA100 changes channels quickly, seems to have better overall reception, has a pretty good EPG, and so far has had no AC3 problems or self-reboots.
