Morning all. I was a (relatively speaking) long time ReplayTV user who got my first unit back when they first broke out. I have always felt it is the cleanest, easiest, and most personal PVR available, but as of about 2 months ago I sold my last Replay unit and have been strictly TiVo. The reason for this is two fold, one, I like the integrated unit, saves me space in the rack and possible problems (fewer components), and secondly, dual tuners. Is the 4000 series going to offer dual 'tuners', and if not, why not? I would think that would be a highly sought after feature, and most Replay owners would have all but demanded it. I know that the unit has no actual 'tuner' to speak of, but why not the ability to record simultaneously from two sources? Thanks!
