jeanrosenfeld Posted June 4, 2007 Report Share Posted June 4, 2007 Part of that depends on the operating system you are using. WinXP Home Edition is not optimized for dual core processors. It will show that you have that processor in My Computer/Properties, but it will not show two processors when you go to the Performance Tab in the Task manager. FYI, I have XP Home SP2, with a P4 CPU with hyperthreading on. It shows both processor performance panes in task manager. Link to comment Share on other sites More sharing options...

WinXP Pro and Media Center are optimized for hyperhtreading and dual core processors. I understand that ALL versions of Vista have been optimized for dual processors. Someone can correct me if I'm wrong. I don't think that EMC 9 has been optimized for dual processors or hyperthreading, but as long as the OS does, you get get some advantages over a single processor machine.

gi7omy Posted June 3, 2007 Report Share Posted June 3, 2007 Just to clarify Gary's point there - this is taken from here "...If you have a PC with multiple physical CPUs - that is, two or more chips installed on the motherboard - you'll need Windows Vista Business, Enterprise, or Ultimate to take advantage of both CPUs. If you install Vista Home Basic or Home Premium, the OS will only recognize one CPU. That's similar to the way Windows XP works today - if have a dual-CPU machine, you need to install XP Professional to use both CPUs. So what about dual-core CPUs? That's different. All Vista versions, even the lowly Home Basic, support multiple cores on a single chip, with no additional configuration required..." Link to comment Share on other sites More sharing options...
ggrussell Posted June 3, 2007 Report Share Posted June 3, 2007 Makes you wonder what the real differences are between dual core and 'real dual processor' computers other than the support chips. Have you seen any comparisons between the two? From that article, it seems to be a Microsoft licensing issue (1 physical processor vs two).

Incoming Posted June 4, 2007 Author Report Share Posted June 4, 2007 That isn't encoding then. If you are using a DVD compliant MPEG already, then 20min sounds about right. In the small 'preview', do you see the movie or a gray image with the work MPEG? if you see the gray image, MyDVD IS NOT encoding. I always capture DV AVI. On my dual core 3Ghz machine, Videowave takes about 1.5X to 2X the length to encode to MPEG 2. I have 2GB of memory and SATA drives and I keep my machine extremely tweaked. Check. Probably not encoding. Link to comment Share on other sites More sharing options...
tbrewst Posted June 4, 2007 Report Share Posted June 4, 2007 Interesting... it doesn't on my P4 laptop. On my new Pentium D it also shows 2 performance graphs for the processor. Link to comment Share on other sites More sharing options...
Incoming Posted June 3, 2007 Author Report Share Posted June 3, 2007 Specifically, I have a 2.4GHz Core 2 Duo (E6600) with 2 gigs of 800MHz RAM. Win XP Home. I was using Disc Copier to compress and copy a ~7GB DVD to a single DVD-R. In Task Manager under the Performance tab, CPU Performance was showing two graphs at full useage. I assumed Copier was using both cores. Link to comment Share on other sites More sharing options...
gi7omy Posted June 3, 2007 Report Share Posted June 3, 2007 It could well be using both - but I've never seen any confirmation (or denial) from Roxio that it does do that. I suppose the best way to check would be to compare encoding times - on my machine (single core) it takes roughly the movie duration to encode and possibly slightly longer (ie, a one hour movie takes about 1 hour) - check the time on your machine - if it's significantly less, then it is using both cores but if it's roughly the same, then it isn't Link to comment Share on other sites More sharing options...

cdanteek Posted June 4, 2007 Report Share Posted June 4, 2007 It should with a Pentium D which is dual core. My laptop is single core with hyperthreading. Gary, go to the view tab, cpu History, then click one graph per cpu. cd Link to comment Share on other sites More sharing options...
cdanteek Posted June 4, 2007 Report Share Posted June 4, 2007 I've had my laptop for a few years. I've tried all options. It never has shown two graphs for my single CPU with hyperthreading turned on. It shows one graph or two graphs for my P4 CPU with hyperthreading. When I change the View tab, cpu History, then click one graph per cpu. cd Link to comment Share on other sites More sharing options...

It is significantly faster. A 2 hour movie, eg. ~7 GB compresses and burns in about 20 minutes. You should double check your times. Link to comment Share on other sites More sharing options...

Oh my times are reasonably accurate - but it does seem that is is optimised for dual core after all - that's the only thing that would account for the vast increase in rendering speed, but. as Gary points out - that's for rendering a DivX file to DVD - if it doesn't need rendering, then that's a different story Link to comment Share on other sites More sharing options...
ggrussell Posted June 3, 2007 Report Share Posted June 3, 2007 And of course, it would make a HUGE difference in what you are encoding from and to. DivX to DVD may take less time than DV AVI to DVD. It would also depend on the codecs used and whether or not those codecs are optimized for dual core Link to comment Share on other sites More sharing options...
james_hardin Posted June 2, 2007 Report Share Posted June 2, 2007 In other words, he he, does it support/use dual cores? Oh yeah. How do I upgrade to 9.1? I'm currently showing ver. 9.0.088. TIA Yes but I don't think anything special was done to take advantage of that. You wait like the rest of us for a V9.1 update… Link to comment Share on other sites More sharing options...
