Most of the DirecTivo's come with a 40GB drive that stores around 35 hours. There is only one setting "perfect" as opposed to normal Tivo's and RePlays which have "basic", "medium" and "high" quality settings. The real amount in hours depends on how compressed the signal is... So, if you record PPV or HBO (not overly compressed) you'll get less hours of storage compared to normal channels.

Anohter advantage to the DirecTivos not having MPEG encoders is that they are way cheap. I put a thread in "For Sale" listing some good deals.

Sorry I kinda hijacked this thread, I really meant to just bring up the fact that if Tivo can come out with little hacks to add features like commercial skip, so can RePlay, so I wouldn't sweat about DM removing that feature (internet sharing would be harder to hack, but that feature doesn't seem as useful).
