My first post- apologies in advance. Curr. have D* Tot Ch in SD, no prem's, have an Aquos 37" LCD, frugal so waiting to go HD til D*MPEG4 in ops to avoid repurchase of HD DVR hdwe. Any info on how they'll upgrade user's HD hdwe when MPEG4 is in use? I've considered switching to E* w/HD(MPEG2) now, since it will still look better than current SD, and I think E* will have to go M4 after D* does? And their M4 hdwe might just be a swap or nominal upcharge. Your comments?
