Have a Motorola DVR via Comcast or other? Bookmark this link.
Comcast DVR’s regularly come under fire for bugs, sluggish performance etc with little information available about software updates, known issues etc. I recently discovered the Motorola DVR/Firmware and Software wiki which reports latest available firmware, changelists, fixed and known issues with each release of hardware, firmware, and software. A useful resource when communicating your issues with your cable operator.
