Hello, I just joined this forum and am new to the HDTV world. I bought a closeout Sony KV-27HS420 HD(ready)TV and the USDigital box at Walmart for $129 with 90-day return priviledge. Overall, I am satisfied with this unit and will probably keep it. The lack of DVI doesn't matter to me because my home theater receiver doesn't have DVI input/output. My revision level is 2.5.47 and USDigital is sending to me the latest. I too have noticed the out-of-sync video & audio and hope this upgrade fixes it. Another member here explained how to directly enter a channel number such as 15-2 (1 5 --> 2 enter) for which I am grateful; but, one has to be fast. My antenna consists of two stacked RS 15-624 indoor bowties into a RS 30db signal amp. I live 30 miles from the sources, in hilly terrain, and can receive all available stations. I didn't find the USDigital signal strength meter to be of much use in setting up the antenna; I had better results connecting to my VCR analog tuner and using my calibrated eyeball to obtain the best antenna position and orientation. Once I had done that the USDigital meter pegged to max and has stayed there. I am aiming through several hundred feet of trees and on very windy days am picking up a bit of video and audio dropout, but tolerable. I am waiting for the trees to be fully leafed before I finalize my verdict. Here's the only feature that I wish the unit had: In the setup menu I must select one output format from 480i, 480p, 720p, 1080i. I would like to be offered another choice called "passthrough" and let my Sony TV make the selection. Right now I have selected 1080i on the USDigital box. That means that ABC & FOX broadcasts at 720p will not get to my TV at 720p but instead at 1080i. Unless, of course, I re-setup the USDigital box every time I change channels -- not likely. On the subject of component HDTV tuners versus TV built-in tuners: I've noticed that very few of the HDTVs (with tuner) have digital audio outputs. So, if you buy one of these without the digital out and want to enjoy the broadcast HD 5.1 audio, forget it. Something to be aware of.
