Recently,whenever I watch a program on 4oD it is fine until the first commercial break. I then get a message on the screen..." This content is currently unavailable. Please try again later"... Any ideas/solutions?
Try rebooting your Freeview box ? I know my Humax is extremely bad at managing memory. Loses the ability to show info after about an hour. If it has issues streaming a channel's data, a quick power cycle tends to sort it.
Could still be some kind of memory (or other resource) issue. Does it go away if you recycle the TV power ? You might want to take it back to the shop. Is it under warranty still ?
