As a result of my audio problems described in this thread, I have just purchased another second hand TiVo. It is the same 6020 version as my current one so am I right in thinking that I can simply swap the 250Gb hdd into the replacement and swap the cachecard and all will work exactly as it did on the old one? Oh, I suppose I'll need to ring cs to swap the account as well? Thanks for any advice. edited: Another question. Can I do anything with the old TiVo without paying two subs?
