DM500S keeps switching back to same channel

[mrblue]

I have a dm500s running jade pli, flashed perfectly, bouquets, skin and epg on no problems.

After a while just watching a channel or flicking through it will always switch itself over to uk gold.

I reflashed box, done everything again and now its doing the same thing, just its switching over to sky sports news every time.

Please help, this is greatly annoying....
