MRV seems about the same on my DECA-enabled DVRs compared with my wired LAN DVRs. Still a few hiccups every several minutes. But my HR21-200 that was networked via a Linksys WGA600N WLAN adapter now works MUCH better since I switched it to DECA. With the WGA600N you really couldn't use MRV without severe pixelation, breakups, etc. I blamed the WLAN data rate. Now, with the DECA, it's just like my other wired LAN DVRs.
