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.
  1. 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.
  2. 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.

If anyone has a similar problem in future, this answer shows the steps I took to be able to read the file into 64-bit MATLAB, which turned out to be necessary due to the file size.
