Sorry I meant to remove this thread. I posted it before asking if the P701AV firmware that you linked worked on the 701AV. I suspect not. Maybe you should create a new forum thread called DHP-P701AV. The only big difference between the two is the P701AV has MIMO while the normal 701AV doesn't. There is also no mention if the newer P701AV's are backwards compatible with the other models like the normal 701AV is.
