Frequently Asked Questions
Why does my Samsung TV freeze when I zap channels quickly?
The hardware video decoder cannot flush its memory buffer fast enough, creating a deadlock between the old channel and the new channel.
What is Zap Time in IPTV apps?
Zap Time is the buffer delay introduced between requesting a channel and rendering it, allowing the hardware decoder to initialize cleanly.
Should I disable channel preview on Samsung TV?
Yes, running video preview while browsing the guide doubles the decoding load on your TV's processor.
