what android boxes work like a pvr ird?Because you are doing that on channels that have streams recorded by the provider. Try doing that on a channel that isn't, for example, International channels on a South American IPTV provider. The BOX has to be able to do this in these cases, as the stream isn't recorded by the provider. Essentially, the box will have to start recording as soon as you have changed channels REGARDLESS of whether or not you have started to record the stream. This is how PVR's function on Bell/DishNetwork/etc. They create a storage buffer.
