Been using Diversity with EyeTV 4, and despite a few little quirks, prefer the tried and tested (!) interface. Recently added a HDHR Duo, and was able to record 4 streams simultaneously. Have just replace Duo with a Quattro, but as others have noted, only Tuners are recognised, even when removing my ancient Diversity. I've seen another post re a Terminal Command for Netstream that permits all 4 Tuners to be recognised. Has anyone found a similar method for HDHR Connect Quattro ?
