Searched this thread but didn't see anything that might resemble what I'm experiencing. I have 3 HR21/200's (0x59e) and all of them have the Power Saving setting "On". When the others are in the "Sleep" mode they are very quiet even when the unit is recording something. One unit APPEARS to be sleeping (No lights on the front panel, etc...) but the fan is spinning away...... I tried restarting the receiver with the Power Saver setting to the OFF position but the box still acts the same. Any suggestions on how to get this box to really sleep?
