Just thought I would throw my thought out here for this box.
Got the box today at lunchtime, tried loading latest patch 07-06-12, my laptop kept blue screening about 70% of the way in, this could be the fault of my laptop though.
Tried the patch from 2-6-12 and it loaded first time.
entered two sea lions and had a flick around 28e, all seemed to be going well until i noticed glitching on some channels. I have two servers one ROI SD server and one UK HD server.
I noticed that it was glitching when trying to clear a HD channel on hop 2 from the SD server, it was connecting to the server first in list and not taking the card that was on hop 1.
I disconnected the SD server and have been on the HD one since, no glitching what so ever.
Downside, the menu layout is crap, reminds me of the old tm 1500 maybe not even that good. I cant get a channel list for 28e and I cant find a channel list editor (don't think it exists)
Good points, picture quality is great, channel hopping is quick and channels clear straight away.
Never had a 5402 so can't make any comparisons,
