Hey guys, I’ve a problem with my antique DM800pvr. At the beginning when the device is turned on, there is no signal on Dvbs2 channels. After waiting about 10 minutes then signals gradually come back. In the meantime, if I zap between the HD channels (DvbS2 ones) I will lose signals so I have to reboot the device. The problem happens only on DVBs2 frequencies and DVBs ones work very well. How can I fix this?
