I have Tivo Series 2 (40GB) need to upgrade to 400GB. Is there a clear instruction of how to go about it? Will it increase my capacity? I have Ver 7.1 of the software. will it automatically detect the extra space and increase my capacity i.e. does it have the limitation in the previous version of only 130GB LBA issue. Will a Hitachi 400 GB work better or a Seagate 400 GB. Any help or links I can refere to will help. I read through the posts and could not find anything straight to the point. Thanks.
