It does seem to be fine I tested for 45 minutes or so through the tuner. I guess it is using different hardware though to broadcast through the tuner as opposed to streaming. I mean I could understand it if all these boxes were the same but bangord has confirmed above he has the same box and has had no issues streaming content using the same plugins as myself. To be honest I am impressed with every aspect of this box aside from this issue but it is a pretty big requirement to be able to stream content to it. I have seen mates with zgemmas (would never touch these myself) with a worse spec than this box and no trouble streaming content. Again it isn't actually that the box isn't capable of streaming the content it just seems give up after 5-10-20 minutes and it does not recover until channel change or stopping and starting the source.
