I've had a ReplayTV DVR for years - It finally died. I also have a Centon InfiniTV USB and an Echo. I've experienced a lot of problems with poor recording quality and WMC crashes (lost tuners probably a lost USB comm problem) also the Ceton requires a tuning adapter with my cable provider (Brighthouse central Florida). Does the Roamio require a tuning adapter when used with a cable card? Can I record the output of the Roamio (all the cable channels are record once locked).
