I used one of the previous models, the P5000, for three years. It was originally purchased as a backup for a photo tour but that fell through due to injury and the viewer was rarely used until I discovered that I could put movie files onto memory cards and watch films anywhere, anytime. This transformed the viewer into a "boredom-killer" and it became my favourite gadget. When the viewer was stolen I decided to replace it with the latest - the P7000 which had a higher specification including a 160 Gb. HDD and direct camera link capability. My joy at receiving my new viewer was almost immediately killed when I discovered that I could no longer play my avi movie files. the handbook which came with the viewer did not offer to decode avi,only avc (my top computer nerds have never heard of this format!) and mpeg4. The pdf instruction manual claimed that the P7000 could handle a wide range of video files including avi but, after trying for many hours, I gave up and contacted Epson UK. After 2 sessions of online chat no progress was made and I am now hunting for a second hand P5000. The P7000 is now unused, gathering dust on a shelf. I am sure that it is a magnificent viewer but, for me, the "improvements " are a disaster!
