Thanks BrianNo, the EPG slowdown is caused by upgrading from a 1.02.xx to 1.03.xx Humax firmware.
"No, the EPG slowdown is caused by upgrading from a 1.02.xx to 1.03.xx Humax firmware."
Also if your HDR Fox T2 has vertical tuner connections ("RE" model) you can only use 1.03.06 or later Humax firmware.
You probably want 1.02.32. Be aware though that this gives you a non working iPlayer and problems recording BBC3 HD and BBC4 HD. It is no longer possible to have a fast EPG and working iPlayer, the BBC have discontinued the iPlayer that 1.02.xx HDR Fox T2 firmware used.
I'll add something once we get to March..I think it would help if an on-screen Web-If message could be displayed for pre-CFW Ver.3 users, as it would help with the inevitable flood of potential users posting "What Has Happened To My Package Updates ! ! !" around April time
