My TIVO 540140 was freezing up and it had to be rebooted frequently. Contacted weaKnees and ordered an HD upgrade kit. Installed kit and TIVO operated fine for a few months and it started freezing up again. I contacted weaKnees and was told to try kickstart. I did and it worked fine for about 2 weeks and it started to freeze up again. I have noticed lately that occassionally while watching shows on my FIOS cable the picture will pixalate, and sometimes it disappears. Could this cause the TIVO to freeze up while recording a show? Thanks.
