The issue of older TiVo models and what to do with them is one that concerns many owners.
The analog Series 1 and 2’s are of course pretty much dead ends. Rare to find a situation where one is reasonably useful. So you can get lifetime Series 2s for basically nothing.
TiVo has been running a promo for a while where you can get lifetime for Series 3 and 4 (Premieres) for $99. First, this a good deal if you qualify (which depends on the CSR you get when you call). Second, this means that a lot of people are putting lifetimed TiVos on the market, lowering prices for those.
So I bought a cheap Premiere XL over a year ago, called TiVo said I wanted to cancel my TiVo HD’s sub, got the deal on that. Two lifetime TiVos for not much.
I had long ago swapped out the HDD on my HD for a 1TB disk. Easy to do and a lot cheaper than going with weaKnees. Much better to do this before the drive fails. (But you can get images from TiVoCommunity.)
My concern about the HD, being a Series 3, is that it can’t handle mpeg4 streams which cable companies are starting to roll out. So my recommendation is to not waste a lot of resources on fixing/upgrading a Series 3. Working, lifetimed 3s are still worth something on the market. For now but maybe not much longer. If you’ve got one and are thinking about selling it, maybe hurry up. (But lifetimed only.)
Premieres are still good for the foreseeable future except for one thing:
Cable companies hate cable cards and all non-cable company DVRs. So support for these is getting worse and worse. The days of buy-your-own DVR may be numbered.
Note that it’s not just HDDs that are failing on these older TiVos. The power supply is a very common source of problems. You can get replacements or if a real DIYer, replace the bad caps.
While Roamio’s are clearly better, etc., you can’t get them lifetimed for $99, yet.
