SD PVR keeps on rebooting at set times

My SD PVR keeps on rebooting at set times. almost everyday between 06h00 and 08h00, and then in the evenings between 18h00 and 20h00. this prime viewing time. My decoder is in perfect working order. I have Googled this DSTV reboot problem and have discovered that my problem is shared with countless other DSTV subscribers who claim that DSTV is trying to eradicate the SD PVR machines by forcing their clients to upgrade to the Explora decoders. This would mean that for the same functionality that I get from my SD PVR, I would have to purchase two Exploras and this goes with additional costs. DSTV wants to frustrate their clients into submission with the unwanted reboots and force them into a more expensive DSTV solution. Surely this is *******. A huge company like Naspers should not be bullying their clients like this to profiteer even more. Monopolies are bad, but will eventually be broken. Fair business practices should prevail, but this does not apply to a giant company like DSTV, it seems...
