I own a TIVO premier XL and want to add more capacity. I want to either replace the stock 1T with a 2T, or add the 1T external WD expander. As per the TIVO HD XL section of the first comment of this thread (http://www.tivocommunity.com/tivo-vb/showthread.php?t=370784), it looks like these are my two main options other than adding an unsupported external hard drive, which I dont want to do. I also dont want to send my unit to Weeknees. Since the thread seems kinda old, I just wanted to confirm that these are my only options, and that I cant easily get above 2T with a Premere XL. If it is accurate to say that there is a 2T limit on the Premier XL's, is this some fundemental limitations of the architecture, or is there any chatter about this potentially being addressed in a future software upgrade? Thanks.
