[QUOTE="RobNorthcott, post: 321707, member: 57999"] Mine does the same thing (but only very occasionally). In fact, it's the most annoying problem left with my system - if I could solve that it'd be completely stable apart from the occasional "tv service not found". I'm using PureVideo codec and an nVidia card, so it seems it's not codec or display driver problems (as yours are different). I recently turned off cool n quiet in the bios because somebody here said that can cause timing issues, but it didn't help me. I'm starting to think the problem is with signal reception. I'm using DVB-S and haven't checked the dish alignment since I put it up over a year ago. In MP's TsReader and TsWriter logs there are lots of "continuity errors" (I think that's what it calls them), that apparently suggest there are bits missing from the received stream. I do get some stuttering when the log records these errors, but it doesn't often hang anymore (it was way worse with RC2). Apparently the new ts reader deals with bad reception better and just tends to stutter rather than crash, but very occasionally mine will still hang like you described (sound continues, picture freezes, and the only way to get out of it is to reboot). Although I'm starting to suspect reception problems, when I scan for channels (and also in the MP log when a channel is selected) the signal strength and quality are both at maximum. I also removed my USB wireless network and hardwired the MP machine to my router using mains powerline adapters because I read here that some USB wireless drivers can be problematic, but that didn't help either (although it was well worth doing because that PC is in a really bad place for wireless reception - I now get reliable WEBEPG updates). If you find anything, I'd love to know! (and if I find a cure I'll post here). Rob [/QUOTE]
