Hi all, This week, I'm upgrading my old 27" 4:3 to a JVC 48" RPTV. One thing I have read is that I'll need to tweak the convergence on the new set. I already have the inexpensive Sound and Vision Home Theater Tuneup DVD and it worked fine for the 27". Will the Sound and Vision Home Theater Tuneup be sufficient for tweaking RPTV convergence? Heck, overall, will I be able to conduct a decent calibration with this disc for a RPTV beyond convergence? I've read that AVIA comes with additional filters for the convergence test. This process for my TV is described in the following thread and seems to be pretty easy with AVIA: Convergence / AVIA Thread at Home Theater Spot Thanks!
