Learning AV net is a copy of Mitsubishi's Net Command. It gives you the potential to use one remote for everything, the difference with the newer Hitachi is if the product you want to use isn't in the tv's internal memory you can learn it button for button. The IEEE connection is great, that way you can record in HD to a DVHS or coming down the pipe, Recordable HD DVD. You will need this connection to do so.
Ok, down to these two sets. Only negative thing I've heard about the vs810 is the screen glare.
The added features of the vx915 are:
Learning AV NET III
Deep Black anti reflective screen
Dual IEEE 1394 interfaces
High gloss black with black trim.
As I'm totally in the shallow end of the pool here what is the Learning AV NET III feature and
Dual IEEE 1394 interfaces?
