How do I check the firmware on Cisco 5050

[Cpybus]

This box is causing a cec system glitch due to green screen. I have read that a firmware update will fix it. I have reset the box but there is still a system glitch unless I unplug the box. I have a nice system and am starting to tire of telus shortcomings- can't get anything over internet 25 in Calgary, can't use cec with my home theatre due to this box issue.

When you reboot the receiver it checks to see if the latest software is installed. If newer software is available you will be prompted to install it.
