Advertisements So my 4 month old Series 2 just presented the Green Screen of Death (GSOD) upon a restart and I've tried all the tricks in the forums to try to get it back in working order to no avail. It just keeps rebooting every once in a while and gets to another GSOD. Called TiVo support and they said since it was a month out of the initial warranty, I would need to pay $50 for a replacement unit. So my question is are GSOD always caused by a bad hard drive? If so, I can get a bigger drive and upgrade the recording space for about the same money as getting another 40 HR replacement unit from TiVo. I did an upgrade of my Series 1 box, so I know how "easy" this process is. Thanks!
