The UnUsual Suspect Posted June 6, 2011 Share Posted June 6, 2011 There seems to be a problem that only effects some users. Our support team believes it may be related to a conflict with external codecs installed on the users system. Can you tell us if you have installed any codec packs or individual codecs on your system prior to the upgrade to 5.1/2 In the meantime, all we can do is recommend you revert to a prior version that works for you and watch the release notes when a new version is published. Sorry for the inconvenience Link to comment Share on other sites More sharing options...
zhenlun89 Posted June 7, 2011 Author Share Posted June 7, 2011 (edited) i install the version of K-lite mega codec pack 7.1.0... does that affect the MPC 5.2 ??? thanks a lot for your help...~~~ ^^ Edited June 7, 2011 by zhenlun89 (see edit history) Link to comment Share on other sites More sharing options...
The UnUsual Suspect Posted June 7, 2011 Share Posted June 7, 2011 At this point it's a theory of mine, but so far everyone who has this problem and has answered this question has installed codec packs. Link to comment Share on other sites More sharing options...
zhenlun89 Posted June 7, 2011 Author Share Posted June 7, 2011 so, can you please tell me what solution i have now... uninstall the codec pack or there are other solution ??? thanks for your concern... really appeciate it... ^^ Link to comment Share on other sites More sharing options...
The UnUsual Suspect Posted June 8, 2011 Share Posted June 8, 2011 My personal opinion is that mpcstar should coexist with existing external codecs, so the problem is with mpcstar. This is only my opinion though and I could be wrong. I use K-Lite codec pack (full) and have similar problems with mpcstar 5.1 and 5.2 with some files. The development team has informed me that the files I'm unable to play all work on their test machines, so I can only surmise that there is a conflict with one of the codecs. You can try removing your codec pack if you want, but if I were you I'd just revert to a prior version of mpcstar until these issues are resolved. Regarding codec packs. Installing conflicting codecs can cause a system to become unstable. Many users choose to only install individual codecs as they need them, but I've found that the k-lite pack saves a lot of effort and I've yet to find any legitimate video that isn't supported by a recent version of k-lite. I personally don't like the "mega" version of this pack. I'm not even sure if thats an official k-lite pack, as it's not offered on the official mirrors for k-lite. I suspect it's been bloated with a lot of stuff that you may not need, so I avoid it. Link to comment Share on other sites More sharing options...
kluelos Posted June 8, 2011 Share Posted June 8, 2011 You could try uninstalling all of your current codec packs, and install the Combined Community Codec Pack instead. It's free, and still being maintained, though updates happen very seldom now. If this does solve the problem, great. If it doesn't, you're no worse off than before, and can be certain that you don't have a codec conflict, at least. Link to comment Share on other sites More sharing options...

The UnUsual Suspect Posted June 9, 2011 Share Posted June 9, 2011 I'm not certain which is at fault either, but I believe mpcstar should co-exist with existing codecs in common use today. Link to comment Share on other sites More sharing options...
jjbladera Posted June 15, 2011 Share Posted June 15, 2011 I reformatted my laptop. With the newly installed Windows 7, I didn't install my codecs yet. I installed MPCStar only. And when I tried to play files that can't play in my previous Windows 7 with MPCStar installed, it actually played. Probably, there is a conflict between MPC Star and the user's installed codecs.

sarahwanderlust Posted July 9, 2011 Share Posted July 9, 2011 I had the same problem and followed the instructions here. I uninstalled the latest version and installed version 5.0. I then can play my mp4 files. I too have K-Lite Codec pack (full) and I can't play MP4 files when I was using MPCstar 5.2 and 5.1. Thank you, um, The UnUsual Suspect. :D Link to comment Share on other sites More sharing options...
The UnUsual Suspect Posted July 9, 2011 Share Posted July 9, 2011 Thank you for the feedback. Hopefully our development team can track down which codec conflicts and make necessary changes. Check release notes when a new version is posted before trying. If this issue is fixed it should be noted. Link to comment Share on other sites More sharing options...
zerojinn Posted July 18, 2011 Share Posted July 18, 2011 5.2 has made certain codes changes to make MPC compatible with K-Lite. In the test environment, MPC Star and K-Lite works well in the sample MP4 file. The development team is working on this issue at the moment, but we are not able to reproduce the error which you guys met yet. We will keep trying, once this error is fixed, you will know from the changelog of a future version. We really sppreciated any detailed specific info on this problem. Would you guys try to uninstall the previous MPC Star and codes, then try to install v5.2 to see if it works? Link to comment Share on other sites More sharing options...
