Advice on VideoReader including missing codec

I have some mpeg videos that I would like to scroll through, and export/crop individual frames for inclusion in a report. I do not have any image processing toolboxes.
- Is VideoReader the right tool, or overkill? I just need illustrative pictures at known times of interest. However, I must do this for many videos.
- VideoReader returns the following error to readerobj = VideoReader('2_1017.mpg'): The file requires the following codec(s) to be installed on your system: MPEG-2. Do I just install a codec pack like this one or is there more to it? Why do I need an additional codec if Windows Media Player can play this file on my Windows 7 machine?

VideoReader() is probably the right tool.
You might have to install codecs if you are running MATLAB in 32 bit mode when your existing codecs are 64 bit, or vice versas.
