Ballzo Guest | I’ve been having some problems with my laptop for some time now. I’m not very experienced with video codecs.
Right now I’m trying to switch the codec that my laptop uses to something else and I’m not having any luck. Its got ffdshow mpeg2 codec installed and it plays but it does not look as good as another PC I have using Dscaler to play the same clips. I’d like to see if using Dscaler on the laptop would look better but I can’t figure out how to make the laptop use Dscaler instead of ffdshow. If I disable the ffdshow in the configuration properties, I get an error message
“Windows Media Player has encountered a problem and needs to close. We are sorry for the inconvenience."
Anyone got some help for me?
I’ve installed, re-installed and un-installed a dozen times I think and getting nowhere.

The way to do it is by going to start, (all) programs, ffdshow, video decoder configuration. (At least that’s how it looks using the 2007-12-24 build). Then click on codecs on the upper-left, and select MPEG2 in the left column in the right pane. Then in the middle column click on disabled. (BTW If you want to try, you can alternate between libavcodecs and libmpeg2 to check things out too).
I’m not very sure what DScaler is, but by the description its main use is as a de-interlacing filter. Does it include an MPEG-2 decoder of its own? There’s a section on the page that says
“The DScaler 4 package contains many dlls that implement different video filtering algorithms, these dlls can be used in certain other applications (e.g. ffdshow)."
I thought it means it’s supposed to work in concert with an MPEG-2 decoder - kind of like post-processing in DivX. Again I don’t know.
As for why your Windows Explorer crashes, I suggest going (right after a crash) to the event log, in the Application log - it’s in Administrative Tools. Usually it will tell you the crashing program, as well as the module causing the crash (usually a dll). It may or may not be MPEG-2 decoding-related.
I wrote a more detailed post on tracing crashes. http://www.moviecodec.com/topics/31759p1.html
You could always forward the crashdump to the authors of DScaler if all else fails.

Ballzo Guest | That is the way I’m disabling the codecs and I have tried switching back and forth between libcodec and libmpeg2. Neither seems to look as good as my other system using dscaler codec. When I try to set them to disabled like my good system is set to. Media player just crashes and shows this in the logs.
Faulting application wmplayer.exe, version 11.0.5721.5145, faulting module unknown, version 0.0.0.0, fault address 0x00000000.

I’m not sure what dscaler is or how it got there but it sure looks better of the two. I just wish I could duplicate it some how.
