In Windows 7 Media Center, I occasionally get the message "Tuner Not Available". The problem goes away after restarting the computer. It can be recording a show, and when the next show comes up, it give me the error message. The device does not have an exclamation mark in Device Manager, and it has the latest driver as well.
It may not be related, but I also get a "Low Data Rate" message sometimes when watching television as well, although this goes away when changing channels.
Are there any solutions?
