butch01:forgive me if i'm wrong but isn't dolby digital is only used by BBCHD which only broadcasts in the evenings so i can cope with this problem til it's sorted.
There's a few C4 shows and movies with 5.1 now as well - not sure about ITV HD as there's rarely anything on which attracts my attention!
From what I've seen on other forums, most people are just venting frustration at Philips and their inability to communicate with their customers. Most companies will issue a list with a firmware update of things that have been addressed, but with this one, it's been guesswork on the part of their customers. People are still not fully sure if DD 5.1 has been included, but it looks like it hasn't from what I've seen others write. On other fixes, it just seems to be so inconsistent - some people say something has been fixed, others say it's still a problem, whilst lucky ones say they never had that problem in the first place. It all seems to be a bit of a lottery and, without any information coming from Philips, people are understandably getting aggravated.
I get your point on having been able to watch the World Cup in HD and not getting too many issues and I felt the same for a while until I started seeing more and more of the bugs others were reporting creeping in as the weeks went on, and then finally getting the "Signal Lost" error every time it was switched on and so I swapped it out. And it's only now I've used the Digital Stream for a few days that I really appreciate how bad an experience owning the Philips was!
I admire your patience if you decide to stick with the Philips, but if you have the ability, I would seriously recommend swapping it for the likes of the Digital Stream or Humax boxes - even if you're not seeing the lip sync issues, or the duplicated recording issue, or the issue of standard definition programmes being recorded instead of HD versions, or any of the other myriad of issues that I saw at one point or other, the other PVRs mentioned just offer a much more user friendly experience from my point of view, and that's ultimately what these consumer devices are meant to do.
Best of luck!
