I have come across the guide problem a few times myself.it will stop replenishing itself then after a few weeks it sais somthing like "to be announced" on all of the lines.the first two times all it needed was a reset but the last time it happened was because the H10 had locked and when i reset it the zip code reset also.tech did manage to figure that one out for me...so i will give them that.since there is no problem with the Denon and others have come across this problem with cable boxes i am going to assume because i have only one DVI input on my tv and i am going to wait out the format change to purchase a new television i am going to have to keep the 990 in the mix for now and just have to deal with the inconvience for the time being if i want to continue to use the DVI outputs.

thanks all for the input and i appreciate any other suggestions.
