I couldn't agree more, this is a major drawback, which is a petty since I liked the product very much.
I travel a lot and therefore spend a lot of time in hotels. At home I use Microsoft Media Center to record TV and than a great package called DVRMSToolbox to convert the programs to MPEG and remove adverts, this output director is monitored my MC. That part works great.
I've tried unsuccessfully to opening video and number of times, sometimes I've left it for considerable periods of time and I still haven't gotten it to work. There's no progress information shown so you have no idea what’s going. Audio works great!
Since I only have a few days of my trial period left, I think unfortunately this will be the end of my experimentation and experience with MC
The UPnP server worked great, it solved the problems I had with my AE Internet Radio connection to MS Media Player. I’ve not tried video but since I need to connect over the internet this isn’t going to solve my problems .
The Theater view looked great and I was considering it as a replacement for the Microsoft Media Center, which I use extensively.
