I want to extract image frames from video clips, both Matlab function "mmreader" and "aviread" don't work properly.  there are following errors for each function:

??? Error using ==> avi_frame at 11
Initialization failed. (General access denied error )
 ---------
??? Error using ==> aviread at 84
Unable to locate decompressor to decompress video stream

Error in ==> avi_frame at 3
 mov=aviread('C:\Users\Samane\Desktop\Angry\tany0275_26_10_2010_15_46_57\tany0275_26_10_2010_15_46_57\Sessions\100\S001-100.avi'); 

could you please help me to remove these errors or use a substitude function?
