Thanks for sending the image and winmfs file. I'm going to give it a shot this weekend so I do appreciate all the info you provided. The friend thinks it does have a lifetime subscription so I'll guess I'll know soon!
This same friend also sold me a Series 3 HD for $25 with a lifetime subscription and after about a year of use it starting rebooting. I'm backing up the hard drive using dvrBARS to see if I can restore to another drive to make sure it isn't a faulty drive. I have a feeling it is the power supply but wanted to try this first. Would you happen to know where I could get an image for this TiVo which is model TCD648250B just in case what I'm attempting doesn't work? Thanks again.
