I have ATV and ATV2 streaming everything around 4TB in total iTunes Library, just finishing the last of my 700DVD ripping and Encoding. Once I am done, it will be nice, but going forward I will only have to rip new DVD's and since I switched from a 2010 Mini to 2011, I just have to attach a USB DVD Drive in order to rip them.
Pretty stoked that I am on the final stretch since I started in June, just a long process and only two movies I can not do anything with Fool's Gold and All I want for Christmas, no matter what I do, I can rip them, but they never encode using HB.
