Lockup for 9865HDC with HDMI or HDMI and IR cables connected--Error Code: Er:21

I have been observing a lockup condition when the 9865 HDC DVR is turned on prior to a connected HD TV (JVC) being turned on.

The fix is to turn on the TV first and wait 10-15 seconds, then turn on the 9865HDC. 

Once it is locked up due to DVR powered on prior to or at same time, there is a front display code: "Er:21".  The only way to reset the Set Top Box is to remove both the HDMI cable and the IR extension cable (if used).  Then reboot the 9865 HDC DVR after waiting for 30-60 seconds after disconnecting power.

Another fix is to not use the HDMI cable and connect via component cables, then there are no more power on lockup issues.

Any suggestions to correct this error causing a lockup with HDMI cable connected to an HD TV?
