Will I be able to download recordings *to a Mac*? (e.g. I can do this on a Tivo with kmttg.. and even better, I can download starting at the paused point, so I can relatively quickly save only the musical guest from a program.) If I can EDIT the recording ON THE DVR even better (similar to what I can do on my Toshiba XS32).
Will I be able to play FASTER THAN REALTIME WITH SOUND? I do this on my XS32 literally every day, and is the major reason I keep using it (since most of my analog channels went away). I dub talk shows & news shows/documentaries (and SNL, about the only scripted thing I watch this way) to watch at 1.5x with sound.
How does it deal with overlap? I guess 6 shows at a time is probably enough without it, but if I can record shows *on the same channel* on the same tuner WITH OVERLAP (e.g. CBS Monday nights, NBC Thursday nights), even better.
