Advertisements I had the same problem develop: bulletproof series 3 with no probs for 2 years and 2 months (original HD, pure OTA antenna) then started freezing during programming,and last night the worst: reboot, progress through THX, TIvo guy screen, freeze on menu... then reboot, and repeat. I thought it was a hard drive issue, of course, like a good TIVO user, and not software, but I unplugged the antenna and immediately the TIVO worked like new!!!!! Able to watch all recorded content, podcasts, and amazon.com downloads, menus speedy, nothing at to suggest any residual hardware probs. However, plugin the antenna and start watching HD, and freezes happen. It even lasts on SD programming for awhile, but start recording, and it slows down tremendously. Reasonable deduction: recent software "upgrades" are so buggy that they freeze the system even with routine ATSC decoding and recording, or analog to digital translation for recording.
