I bought the slightly pricier GHDD1785DVBT (from elsewhere) as it had twin digital tuners for a very reasonable price. Plus points - an attactive and compact unit with easy to use menus and EPG, the picture quality is great and hardly ever any picture interference. On the negative side, and most annoyingly, even on standby it regularly switches channels on the TV (eg when watching DVDs). The sound freezes up or becomes unsynchronised when watching and recording simultaneously. Apparently some of the the infrared remote commands seem to use the same frequency as some of my other non-Goodmans equipment. I returned and replaced the box at the retailer but the faults appear to be design or engineering flaws, so this baby is going back as soon as I can watch all the backlog of recorded programs.
