HR21P issues with directv screen saver

[jager0320]

I'm having issues with the Directv hr21P receiver. The screen saver kicks in after only a few minutes, doesn't matter what channel is on (i.e. not just XM music channels), and sometimes it will auto-change to an invalid channel (1077 for example). Has anyone else seen this problem? I checked and I am running the latest firmware release from Directv.

Thanks,
Brian
