Hi There Mister - When I had my SD-PVR - I encountered this problem once or twice as well! The solution is to unplug your SD-PVR from the Mains - and let it do a full reboot - this will usually solve the issue - if not - select the required programme in the VOD menu - and press the RED button on your remote to delete the episode - and it will request a NEW copy to be downloaded!
Hi Mister - try logging a postng on the DSTV forums - www.dstv.com - you have to register there first before you can make any postings - and see if you have any joy with a response - the fault might even be logged there already - or - as a LAST resort - log a fault with the DSTV call centre (031) 710-2222 - and see if you get any joy there!
