I've been recording the "Star Trek" repeats in the early hours of Saturday mornings for the past few months.

I've quite often had a burst of picture break-up in one of the episodes. I'd thought it might be transmitter problems, but now realise it's always at 03:30.

I'm guessing this is some effect of the 4TV EPG download. Have others noticed this problem? Is it easily preventable?

(I've installed a 120GB drive, so would things be better with the original 40GB?)

I know this doesn't help, but on my standard machine I've never noticed anything wrong with those Star Trek episodes.

Not being near my machine at the moment I can't check, but can't you disable the downloads via the hidden engineering menu (Menu-6-9-1-0-0-4)?

Obviously you'd need to reactivate them afterwards so you don't start losing your EPG.

You can't turn off the downloads but you can defeat them by ensuring both tuners are recording between 0300-0400. So as well as your intended programs record an hour of something insignificant at the same time.

The only drawback is you can't record back to back programs with overlapped padding. If you want to do this you'd have to have 2 dummy recordings to fill in the gaps before and after each program on each tuner. Fiddly but workable.

Seems like there are a few Trekkies on here! I too have been recording these and not noticed anything odd, though I skip the odd episode if I don't like it (ie Tribbles) or have just seen it (still getting through my 3rd series DVDs ). Will keep an eye out for any issues though.
