Advertisements I replaced my old Tivo with a new Humax DVD from Weaknees. The old one was freezing and I assumed it was the HD. I have also added a continual UPS power supply. The new one worked fine for a few days, but now it is intermittently freezing also. So, 1. COuld the ethernet connection be a cause. I have recently added a new switch (after the problem occurred) so I don't think it is the switch, but I don't see how this could be the problem. 2. Any other suggestions?
