Hey all, I currently own a 40 hour Series Two SA TiVo which has served me faithfully going on a year. I'd like to get more hours though and am thinking of upgrading my current unit with one of the kits availiable online (probably from Weaknees). I'm a little afraid to do it though for fear that I may run the risk of ruining my TiVo. Do any of you have experience with this? is it fairly simple to do? I'm not the most handy person and have had little to no experience working with computer hardware, will it still be pretty simple for me to do? Please share all positive and/or negative experiences you may have had with this. Thanks!
