I have the answers. The first thing I need to know, is whether or not you have any experience modifying pcb boards and or soldering? If so, I can be of much more help. LMK, and I will post links to everything you need, and or walk you through the process. The mods on the 4960 are almost exactly the same as the 3950/60, except the boards are different, and the placement of parts/wires on the pcb is different. The 39xx series is much easier fwiw. Or, you could always pay someone 200 bucks to do it for you, though I wouldn't! Last ?ion, what is the primary use of the player for? If you are going to all the trouble, the 4960 plays dvd-a, which is a huge part opf why I bought it.
