I have problem to run few files

[adicoto]

WMV, AVI and MPEG doesn't have common codecs. So, there is no codec that can be used to play all 3 files and be missing.
So, I believe you let BSPlayer install codecs through codecmanager, and they didn't installed because UAC was not disabled or Program files folder it's still "read only" . Windows 7 doesn't report that the filters didn't installed. Nice trick. Anyhow, WMV should be runing without any other codec.
Suggestion 1: download and run MPC. Try the files you mentioned. If all 3 files play OK, codecs are with the problem. If not, then the files are fakes, downloaded from internet.
Suggestion 2: UNinstall BSPlayer and it's codecs. Uninstall codecpack. Reinstall codecs or codecpack. Install BSPLayer without downloading filters.
