Tiberious, Has your IDT got the option of an auto update? (Menu 7 = technical information. 3 = auto update) You could give this a try. I have a Pioneer S.T.B. that used to freeze up all the time especially if you used the P+ P- to flick through the channels but the update seemed to cure it. (It still freezes occasionally but nowhere as bad as it was). Have you tried connecting the Ariel only to the T.V. is it just as bad? Give the update a go you never know! Hope this helps you M8. Regards Tel.
