Hi everyone first post. My 30 hour Hughes TIVO died (Green Screen saying error) and I don't want the stupid direct TV DVR. I have one and it sucks. I bought a used Direct TV TIVO off ebay before I knew I could buy just the hard drive. What should I do to get this fixed now? Should I swap out the bad TIVO with the new used one or just switch the hard drives? What is involved with the switch? Thanks!
