Hi guys, I've bought a original used Vu+ Duo, which I'm using only with usb dtt stick thru a 5v powered hub. The box seems to work good, but sometimes, while i'm zapping thru channels, it looses the signal and no channels show anymore until I completely reboot the box. Sometimes, while I switch it off from the main power button and I reboot it too quickly, it only shows red light without any "starting..." display. If I shut it off for 4-5 seconds, it reboots without issues. Now I'm running OpenPli 4, but this problem shows with any image. BTW, I have another Vu+ Duo that works fine. Anyone can help me to find out what's the problem? THanks!
