Nice attitude! It is always the fault of the poor technically inept user who does not have 32K+ posts to their credit! The sheer typing you have done boggles my mind!
To repeat for the umpteenth time: I had NO PROBLEMS with Roxio Creator 2009, 2010 nor 2011.
I have amply demonstrated a repeatable reversible problem with Windows Media Player 12 and a conflict with a specific Roxio Creator NXT Pro installed DLL: to wit: dsfOggDemux2.dll
If you will look at the version history of this set of CODEC libraries used by Roxio you will note that they are "pre-lease" www.Xiph.org is up to at least Version 1.3.x currently.
Rename this DLL and WMP12 works fine for MPEG-2 files!
Despite the supposed program dependencies: Windows Media Central will play my MPEG-2 files. With or without NXT installed.
Windows Media Player 12 will not play them with NXT installed. These Windows components install and uninstall together so independent investigation is impossible.
After my 1-17-2014 re-imaged system drive (which got RMC working again). I noticed very subtle instabilities within MM14. If I did VIEW -> DETAILS from the menu bar it would stop working.
If I worked carefully just in the RIGHT PANE I could get it to display and play my MPEG-2 files. But unlike Creator 2009-2011 double-clicking an MPEG-2 file never successfully just plays these files.
I tried adding my locations to Roxio MONITORED folders. That appeared to work but no longer. Upon reboot, and apparently now because I have "used" MM14 so frequently it appears on the HOME pane of RMC, it will take 10-15 seconds to start (displaying my files in a list, at some of them) but then crashes. Each subsequent launch crash is VERY RAPID. Must be that screwed up ntdll.dll on my system! I do not have sufficient time to make any resetting of folders or filters - the crashes are too quick, to get back to a working MM14 configuration (if I am even sure what that is / was).
FWIW: SFC / SCANNOW comes back clean. But surely there be must something it is missing on my screwed up computer.
Another recent curiosity (if anybody cares, which I doubt): Shortly after (minutes) when I added my MPEG-2 folders to the Windows Video library (which uses a WMP permissions service to insure sharing- right there in the EVENT VIEWER LOG). That is when MM14 starts showing instability, more or less, forever forward once it does STOP WORKING for the first time.
Basically WMP12 and MM14 just hate each other (but only on my stupid computer).
Actually on my 2nd internal laptop drive I do have a very clean, minimal installed Windows 7 bootable system.
When I feel up to it I will work the 16+ screws and reverse these drives and install NXT Pro over there. It might be 158 Windows Updates behind so it will take a while.
BTW: Corel WinDVD has no problem playing my MPEG-2 files at all, either.
How can it be "my computer" when Roxio Repair install, on its own from the DVD, ALWAYS wanders off into the weeds and recopies Triple Scoop Music content and DOES NOTHING to look for missing DLLs and or programs (I deliberately tested this by removing large chunks like the MM14 folder and the Roxio Common folder to another drive. NOTHING THERE IS EVER FIXED / RESTORED / RE-INSTALLED). Useless music files ALWAYS "fixed", real program problems NOT SO MUCH.
So what kind of "repair" function is this? What could "my computer" possibly have to do with something running off an install DVD?
I have looked at the Roxio Install logs - from mid January install -- and they are "clean" (error free).
At this point, good money after bad or not, I am going to put in for a PREMIUM ONE INCIDENT SUPPORT TICKET.
I am perfectly willing to have this $25 or whatever go up in smoke with no satisfactory resolution.
Maybe I will get another chance to fill out one of those Corel Quality Survey forms!
