I really want to get my HT system be as good as it can possibly be, but I need some help with achieving that goal. First off, I need to calibrate it. Yeah I know that is something I should have done right away, but I didn't really think it was necessary at the time I got into HT. So, I know that I need an SPL meter from RadioShack. I also know that I need a good calibration disc, either Video Essentials, Digital Video Essentials, or Avia. Which one of those three do you think is the best? I saw that Deep Discount DVD has DVE for only $17, so that might be a good option. Another question about calibrating. How much better will it make my picture and sound? Can I expect a mind-blowing difference, or a little difference? Secondly, I think I have a Sony KV-32S20, but I don't know for sure since I can't find the manual and I am too lazy to look behind the TV. Anyways, on some movies, like Back to the Future: Part 2, there are horizontal bars that roll vertically on certain parts of the picture. Here is a scene that it happens on. The parts that the bars roll on are circled in the first picture, and the second one is zoomed in on the pattern of Marty's vest. Does anyone know what could be causing this rolling? Third, I want to know where my crossover level should be set. I have got a JBL SCS135SI speaker set, and my receiver has crossover settings of 80HZ, 100HZ, 120HZ, 150HZ, and 200HZ. The speakers are set to small, FYI. Forth, I would like to know what you think of my HT. This is one that was done on a budget, so it isn't nearly as good as what some of you have. Receiver: JVC RX-5020VBK DVD Player: JVC XV-F80BK The speakers and TV were already mentioned. I have had that TV for at least 5 years, but it still works really well. Thanks for the help!
