I had this problem last couple of days, hard reset usually takes care of it. Now nothing does it and the reset takes 45 minutes! I can watch TV but am out of luck on interactive , and DVR function. Hard Drive system check in green, but it will not let me do a hard drive diag(greyed out). Guide info seems to be there but sometimes tells me it is outdated, an update does no good. I have already called for A new 722. After listening to a scripted trouble shooting CSR, he finally agreed to send me a New one. I think my hard drive has taken a dive. CSR(script) could not verify. Anyone have any other Ideas??
