I was wondering about the pronounciation of the 'y' as a 'j' sound. Before this, i only heard the woman use this pronounciation, and based on other things I've heard, i assumed this was a cuban accent. Then the guy used it, and I'm wondering is this an accent or how its supposed to be said in 'proper' spanish?
In Spanish the "Gerundio" is actually our "present participle". It can be confusing because our word "Gerund" is used only for the present participle when it is used as a noun. In the present progressive tense in English, we use the present participle with a conjugated form of the verb "to be", but we use it more often as we like to report what we are doing as we are doing it and even use it for the future with a word that indicates when. In Spanish, they cannot use the Present progressive for future at all for it is like saying "I am in the middle of doing this." http://spanish.about.com/od/progressive-tenses/a/present-progressive-tense.htm
It is confusing, because it literally means 'they eat' and duo switched back and forth between 'they eat' and 'they are eating'. Then -endo is introduced, and then we are going 'wait a minute, what just happened here?' All i can think is that in english we can use 'we are' to mean this is what we are doing right now (-endo), and this is an activity that we do regularly. For instance, if a child knocked on the door and asked to play, a family member might say 'I'm sorry, they are eating at the moment, please come back after dinner.' This should be 'comiendo'. Or suppose the children had a tummy bug, and someone asked for an update on their health, Mom might say 'Oh, its such a relief! They are eating now.' They may not be eating right that moment, but are capable of eating. Maybe this is what is meant by 'ellos comen'. I'm not very good with grammar, but i think has something to do with tense. Not only do you have past, now, and future, but also a neutral tense that applies to a state of being, like 'i eat bread'. It's a regular part of my diet, but I'm not telling you anything about when i eat it. This is guess work based on other comments i have read, hopefully i am close.
