I have owned both of these units and you must weigh the pros and cons for your self. Solely on video, the panasonic is unquestionably better as it should be. It is a 3rd or 4th generation dvd player as opposed to a dv-09 first generation. Also, the Panny has newer technology, as in progressive scan, furthering it's video dominance. However, as an interlaced player, the DV-09 still rules so, if you have no current or future need for progressive scan, go with the DV-09. As an audio player or transport, I favor the Pioneer. More solidly built, very reliable transport motor, outputs 24/96 and has a fully isolated copper chassis. As a side note, I had the DV-09 and sold it for the 37. All of the advantages of the DV-09, half the price, newer technology, progresssive scan and faster access to chapters and menus. Oh, I happen to have one for sale on Audiogon :)
