I find that the info object often does not have the exact key you are looking for, many different encoders use slightly different variants, or don't include it at all. My best advice is to print out the info for several of your files and look for patterns. Also there are some tools for working more directly with EXIF data, these might also be useful. Unfortunately this area is not really standard, so every solution is likely to break down sometimes.
