reading MOV files

I'm a long time Matlab user, but newish to Macs and video formats. I'm having a problem reading in .MOV files. I can define the obj with mmreader, and all seems well:
EDU>> info = get(obj) info = Duration: 155.1550 Name: 'CIMG0454.MOV' Path: '' Tag: '' Type: 'mmreader' UserData: [] BitsPerPixel: 24 FrameRate: 29.9700 Height: 192 NumberOfFrames: 4650 VideoFormat: 'RGB24' Width: 432
But when I try to get the first frame it fails:
EDU>> tmp = read(obj,1); ??? The frame index requested is beyond the end of the file.
Error in ==> mmreader.read at 74 videoFrames = read(getImpl(obj), index);
Anyone know why Matlab thinks there are no frames? The file is certainly not empty. Am I better to convert to mpg? (I can, but have to use a computer on the other side of campus. Would rather get the .MOV file to work.)
Thank you for your help!

There is a bug report indicating this is problematic on older versions of MATLAB:

Bummer. My matlab is only 1 year old, but I guess it's got the bug. I'll just convert to mpg. (The frame read works for that.)
Thanks for the reply!
