I was flipping through the options on my Comcast HD settop box and stumbled across HD movies on demand from Starz! and Encore.
After a a few clicks Shopgirl appeared on screen in vibrant colors and 6-channel surround sound. (OK, selection is an issue, but it is an issue with HD-DVD and Blu-Ray, too.)
Unlike HD-DVD and Blu-Ray, I didn’t have to spend hundreds of dollars on a device that will likely be a doorstop in a couple of years.
Assuming the studios are wise enough to license content for the service, the biggest impediment HD movies on demand faces is Comcast’s lethargic, poorly thought out On Demand interface. It seems to be designed under the principle of “Why make things 1 step instead of 4?” Trying to explore the offerings is painful. That, and the graphics look like they are being driven by a Commdore 64.

Yeah but you could get a PS3 — kill two birds with one stone 🙂
Why get an overpriced doorstop in PS3 though when Comcast could retool the interface and keep your entertainment system uncluttered? Besides, Ps3 wants you to get an additional remote control to use theBlu-Ray.
SalsaGirl makes a great point. Not only do you not have to shell out money for a box, you don’t have to deal with another box to connect to your entertainment system or another remote. Plus, if it breaks you don’t have to pay to fix it.
