I am currently in the midst of a dilema. I have a HDTV running off of a non progressive scan dvd player. I also have a poor sub, an 8" klh that really sucks. I don't know which one to replace first. Should I buy the progressive scan dvd player so the picture looks oh so sweet. Or should I buy the 12"sub, so the sound is filled out all the way and I can feel the bass. I can't decide. Which would you buy first? I need some help.
