There is one other option available to you. You could build yourself an HTPC and get one or more of the Hauppauge HD PVRs. The HD PVR can record HD content from a cable box or HD receiver via the component outputs with no DRM issues (at least none that I'm aware of). Granted, this is not the most elegant solution but it does allow you to record unencrypted content from any HD source. OTOH, a hacked S3 Tivo or Tivo HD can do this for you for far less expense but since you seem to have no interest in hacking your Tivo I see no other recourse for your situation.
Hacking Tivos is a hobby for most of us and not necessarily a means to an end. This is a forum for Tivo hackers and hobbyists that want to learn the process. If you have no interest in Tivo hacking then you're simply in the wrong forum. You will probably find yourself more at home with the folks over at the Tivo Community Forum.
As for the investment in learning the process being unreasonable, I beg to differ. I will admit that it does take a lot of reading and searching to find what you're looking for but everything you need to know to hack a Tivo HD or S3 Tivo is right here in these forums. You just have to decide what having a hacked Tivo is worth to you. Just remember that you have to pay to play and that you have to play to win.
Please don't PM me or any other members looking for personal assistance. You'll do better by posting (after you've exhausted the search feature, of course) and taking advantage of the collective expertise of the membership instead of a single individual that may or may not be able to help you. Thank you and enjoy your stay at DDB!
