I got my 37CV500 from Vic at Sight and Sounds as well.
So far the unit is good naman. Although I use it mostly for cable, picture quality naman is pretty good. Since I'm on dream cable, their box had composite and s-video output. I tried both and there is no difference in picture quality. Recently I saw the Singapore F1 and the picture was very nice.
The sound is awesome. I turn on the SRSWoW feature and its fantastic, even on cable movies. The TV is currently on its factory setting and for day shots, the pictures are clean and crisp but for darker shots, i think I have to fine tune it pa.
DVD is a lot better. Using the component connection, very clear and crisp ang pictures even on day or night shot. I'm just having a hard time selecting picture size I should be using, Wide, Cinema1 or Cinema2.
Now, I'm just waiting for HDTV and cheaper Blu-ray DVD players.
