I may have an opportunity to lifetime either a Series 3 (OLED) or a TiVo HD (TCD652160) for the $99 offer. I'm trying to decide which one would be better to have a lifetime subscription on. Here is what I know that could influence the decision, but maybe there are some other factors I am not aware of: Series 3 (OLED) requires TWO cable cards in any circumstance TiVO HD (TCD652160) can work with one M-card, but has a smaller stock hard drive (I think) the Series 3 (OLED) seems more prone to the power supply cap issue I know I can upgrade the hard drive in the TiVO HD (& have done it in a Series 3 OLED) so that might not be as much of a factor. I already have a Series 3 OLED and I like the front panel display options (clock, recordings, direct buttons, etc.), but this probably shouldn't be a huge factor for getting a lifetime subscription. Which one would be better to have a lifetime subscription on?
