I have a Series 2 which has been working well for years, and is eligible for the current lifetime transfer deal. I'm thinking about taking the offer, even though I probably won't purchase an HDTV for perhaps another year. I've read at the FAQ that the TivoHD supports a 480i output format. I also am on a digital cable tier, so I know that I'll have to get cablecards to continue recording those channels, but that I should then be able to record two digital channels at once. I'd like to upgrade now, to get dual tuners and new hardware in the short term, and to have a smooth upgrade path to HDTV when I'm ready to make that plunge. Does this sound like a reasonable course of action? Importantly, will the TivoHD function fully at a fixed 480i resolution? Can the apps be coerced to run at 480i as well? (The HD FAQ isn't clear on this.) Is anyone already doing this?
