Just got my two new NOVA-TD's and at a first glance they seemed to perform well. Closer inspections however revealed that I see exactly the same issues as Soeren. Watching live TV with VDR on one adaptor while constantly retuning the other one using: while true;do tzap -x svt1;done gives a short glitch in the VDR stream on almost every tzap. Another €100 down the drain. I'll probably buy four NOVA-T's instead just like I planned to at first. /Magnus H
