Some added info - I did a bit of testing on my Dell Latitude D620 laptop. Trimming still does not seem to work, but I did not experience any freezing when moving around within videos. This laptop uses an ATI based on board video chip - Intel duo-core processor - with only 1 core operating, thanks to some corporate IT folks who didn't realize a duo-core machine requires a different load image than a single core machine . . . . Could the nVidia chipset in my home tower be what the Roxio program cannot deal with, even though the video card is ATI?
Good Question in ref. to the Nvidia chipset. I have loaded the EMC9 software on my Dell 600M computer which has an ATI mobile Radeon 9000 graphics card. Even though my laptop is slower, all the functions of MyDVD have been working as advertised for at least a week with no hang ups, freeze ups etc. Also, on my desktop with the Nvidia card, using Windows Media Player 11, I can open and play every one of the Roxio EMC9 preloaded video and audio clips with no problems whatever. So, after wasting numerous hours on this program with absolutely no help from Roxio Tech support (that is a subject for another day), here is what I think.
My guesstimate is that the Roxio's MyDVD software does not interface well with an Nvidia graphics board and there is some kind of conflict between how MyDVD embeds and runs its videos. I think it is either a conflict with Nvidia or with Windows Media Player as I believe that it is interfacing with Windows Media Player to do this. I have seen suggestions to roll back WMP 11 to WMP 10 or below, but that makes no sense to me to go back to a previous version of WMP just to run EMC9. This is an issue that Roxio/Sonic should fix.
Anyway, just some thoughts. by the way, MyDVD has become totally unusable again.
