So Last September I had a lifetime S1. I bought a S3 and paid my 199 transfer fee. My S1 has worked with the 1 year prepay that they gave everyone who did this. Questions: 1) If I buy a TivoHD, can I transfer what service is left on the S1 to the S3? 2) Regardless of if I can transfer in #1 above, what kind of multi-unit discount will my TivoHD be eligible? 6.99/month? 3)Finally, if I didn't do any of the above, what per month would I be paying for my S1 once the year prepay is up? Would it get the 6.99/month? Thanks guys, I'm still very confused by the present scheme of pricing as it pertains to the S3 swapping/complimentary 1 year service.
