Well two days ago I was able to order a replacement 722k. Tracking info says it'll be here Tuesday, 2nd day air. I don't know if that is fast or slow in regards to shipping?
Today, after many attempts, I was able to get the receiver to boot up. I quickly attached an EHD. Unfortunately, since this was the first time I had used an ehd, the receiver had to format the drive first and reset. After the reset it tried to boot up again but couldn't make it. I fiddled with the receiver for an hour trying to boot it up(so I could transfer the recordings) but was unsuccessful. Will try again later.
