Thanks for the pointers. My search didn't turn these up, but I recall seeing that my search was limited to a year's span and I didn't see how to work around it. As I read them both of them are talking about using MyDVD over a virtual terminal. Which isn't allowed. And which I'm not trying to do.
To answer all of (I hope) your questions:
Roxio Streamer: Pretty sure I never installed it, unless it's a part of Roxio 2012 that I am not aware of. I do have active network services running on this machine, with ports poked through the router/firewall as needed like an Apache HTTP server, an FTP server, an SMTP server, a PS3 media streaming server, a TiVo Desktop Service, and it supports remote terminal access like all Win7 Ultimate machines do. The services handle their obvious purposes. MS/Windows doesn't have telnet support enabled (I just tested it.) I use printers connected in my home LAN to another computer and sometimes I telnet (remote terminal) to that computer to control the attached scanner. So there's a good deal of possible network activity, though most of the time the only thing happening is that all these servers are listening.
Remote Connections: The control panel tool shows no remote connections. This feature appears to be for "outgoing" connections to other computers, rather than for supporting in-bound telnet sessions, right? I can force the error to occur by remote logging into the machine while MyDVD is running and when I do the Remote Connections screen still shows no remote connections.
Virus: I run Norton Internet Security and it checks all the time and/or in the background. It is configured to do a full scan weekly.
While my Win7 Ultimate does support remote logins, and I do ocassionally access my machine that way, I am ONLY using it with a locally connected keyboard, mouse and monitor (over DVI). No one else is using a remote login session during these MyDVD sessions, or else their login would kick my off through the wonders of Windows Fast User Switching feature. It is not a multi-user environment.
There is only one monitor, here, in my office on my desk. It's the one I'm using. It's connected to the machine via DVI. The graphics are embedded in my processor, I don't have a separate video card.
My guess is that Roxio is looking for the presence of some service and using it to claim that I'm accessing the machine remotely. But guessing and wishing don't generally lead to a solution. "TermService" is running all of the time listening for incoming connections. But almost all of the time there isn't one, and if there was I would know it since I would be asked to agree to be "Fast User Switched" off the machine and my monitor would then show me at the login screen.
Network: The Win7 U's "Network and Sharing Center" shows that I have a network defined on the computer. It is connected to a "Home Network". I share a couple of drives for remote access to the other machines in the house who (typically) use the machine's disk array for backup storage.
Did I answer everything?
Thanks for your attempts to help!
