i have a eurovox max v. have downloaded latest software and powerscanned the frequencies, not all channels are found most of those found are un watchable but several are okay.
if the picture is breaking up a lot its more or less something to do with your pipe or scart just make sure they are all connected right and pushed in tight and if you have another box double check it on that pipe or even try your box somewhere else in the house just to rule out possibilities
just make sure its not a clone even though its a max v there will still be clones out there i would try flash it with the (10/04/08) firmware and see how that is and then flash it with (18/04/08) firmware to see how it works on both of them .. just an idea
