I will be replacing my HR10-250 with an HR2X box in the near future. I also have an old R10 that has been deactivated for about two years. These TiVo boxes work great and have been rock solid. I am simply transitioning to MPEG4 HD boxes for my last line. As they both work fine, I thought I would sell these as SD DVRs through Craigslist, EBay, etc. My question is, should I remove the access cards before selling them? I seem to recall that personal information on my account may be on an access card and that I should not sell it with the unit. The new owner would then have to purchase a new access card from D* and activate. Comments?
