No problems installing on my Treo 680 here either. Requires a password, which I haven't had in the past, but no big deal, I set an easy to remember password up, and was good to go.

Here's some relevant information:

-Cingular Treo 680, full signal (the tower is less than 1/4 mile away), unlimited data plan. 3g sim chip.
-Use port forwarding at home through router. I can set up QOS if you guys feel it would help my quality.
-Home ISP is Time Warner Cable, cable modem, little used upspeed (no downloading media).
-Slingbox is slingbox tuner, newest firmware (Nov 06, I believe).
-Using analog tuner in slingbox for viewing.

Comments:

The video looks great, but it is choppy unless I keep my Treo perfectly still. I can't imagine using this in a moving vehicle as is. Maybe you guys can put an option in to increase buffering and/or video quality?

Changing channels via the number keys isn't super intuitive. Maybe a transparent overlay over the screen showing what numbers you are pressing?

I'm pretty happy with this. It gives my Treo so much more functionality. Thanks, team!

Mega- What you said about the constant polling rung a bell- I use Blackberry Connect on my Treo680 for email, and it polls on regular intervals. I may need to look into suspending it when I watch the slingplayer.

I did set the sound to mono-high. I'll play with the mono-low and see if thats acceptable.

BTW, didn't mean to hijack your thread, Sluggo. It just works as an ongoing thread for our model Treo. :)
