Currently, in order to tell if a program is successfully recording, a user must do one of these:
* Open an instance of MC on another client, change the library to the TV DVR PC, click on Television, click on list of Recordings.
* Go the display of the TV DVR PC, open an instance of MC on the TV DVR PC, click on Television, click on list of Recordings.
* Use Windows Explorer, go to the TV DVR PC on the network, look in JRiver/Video and see if a file with the name of the program has been created.
It would be much easier to do what some other TV programs do, namely have a tray icon mouseover display a tooltip with a list of currently recording programs.
In fact, one freeware program has a small "notifier" program that can run on any PC in your LAN, and puts such a tray icon on that PC. But that seems much more programming work than just adding the tooltip to the PC that is doing the recording - which would be much more convenient than any of the above methods.
Oh, and what would be really helpful would be to make the tray icon red whenever a program was currently recording. That would be equivalent to the red light on the front of a physical DVR. (But I don't know enough about Windows tray icons to know if that is practical.)
