Have also been having iPlayer hang (spinning disc) issues for a few weeks and it can happen several times in one program. Watching ‘Have I Got News for You’ yesterday morning it stopped three times which is very annoying in a 30 minute show. The way we fix it is to press play again which usually gets it going again.
We have a HDR1000S CAT5 connected to a Gigabit switch internet provided by PlusNet via BT Infinity (BT Wholesale Test Speeds: Download 59Mbps, Upload 14Mbps and Latency 20ms)
A wired PC via a browser and wireless iPad with the iPlayer app work without any problem.
Its almost as if the iPlayer application on the Humax is not buffering the content correctly.
Lets hope there is a fix soon.
