Just an update for those that might be curious. After I got my replacement THD, I proceeded as described above. This allowed me 2 weeks worth of guide data and the ability to continue using my Season Passes and other TiVo Plus features. After the guide data expired, I reconnected the wifi adapter and setup the TiVo for my network. This of course reset everything to TiVo Basic as expected. (Side note: Among all the other restricted features with TiVo Basic, the onscreen guide allows only TiVo Classic view and not Grid View.) Either that night or the next day, I had a message waiting on the TiVo. It was asking me to try TiVo Plus service free for 45 days. Can you see where this is going? I knew you could. I signed up for the free trial and was accepted. So I have another 45 days of TiVo Plus on my (now) standby DVR. Thanks TiVo!
