Definately a really weird situation, I must say. Once the sub was unplugged, we saw clear picture, etc. Once the sub started to shake the earth beneath us, the screen would begin displaying horizontal lines, until the bass wasn't as prevalent anymore.

I do recall Tarun saying (after my younger brother and I left) that he put his hand on the DVD-player, and that seemed to have gotted rid of the lines.

As a result, it's gotta be the DVD player...becuase he even tried it with the Xbox360 and there were no lines...correct me if I am wrong here?

Must say though, the projector really is cool...and the display is most amazing. And here, I thought my puny 32" LCD HDTV was something to write home about...hehe. NO more!
