I believe there is also enhanced networking capabilities - although I am not sure about this one.
I bought the more expensive one for the 5.1 analog outputs
There are four (4) differences between the two players.
1) The HD-XA1 has an RS-232 connection on the rear that the HD-A1 doesn't. This is great for systems controlled by the Crestron system or similar products.
2) The HD-XA1 has Stabilizer Feet to help reduce vibration and increase signal quality.
3) The HD-XA1 has a Motion Activated back-lit remote. While the HD-A1 remote resembles the XA1, it doesn't have the motion activated feature.
4) The HD-XA1 has the mechanized, brushed aluminum panel that folds down to allow the drawer to open and close and it hides the USB ports on the front.
This list was given to me by Toshiba's HD DVD marketing division.
