The premier that is hosting the mini works with Comcast on Demand just fine. I am using 1Gbps Ethernet for connecting Mini to my home network. The first time I tried Comcast On Demand on the mini, it listed the shows just fine but when I tried to play one, I got an error that it has run into some error and I should try later. (no, I did not write down the error). Just to make sure On Demand is working, I went to premier, watched a couple on Demand shows and then came back to mini and this time I can't even get the listings. I get an error with some reference what seems to be a server address with some TiVo and Comcast in the name. And then it asks me to call my service provider. But knowing how clueless Comcast tech support is, I am not going to bother. They are going to ask me if I have a Comcast DVR and claim that I must have a Comcast DVR in order to get on Demand and I am sure they have not heard of Mini. So, anybody got their mini working with On Demand?
