At least your DTivo's are working! Mine decided to Green Screen on me a few days back and now i'm hosed. Running diagnostics on the discs as i type... but i already did that once to no avail. I'm going to increase the swap partition, and if that doesn't work it looks like i'll be trying to hunt down an image file for an HDVR2. Blah... the worst part is that if the Tivo dies so does your DirecTV.
