Stuck But… Anxiously Waiting

I haven’t been posting like i should but i have learned a ot about myself from this project. Right now have my whole project mapped out but i am still having problems with the conversions. I downloaded the codec for mts and it plays but only the first 30 seconds after that it times out and i do not want to put everything together and no be able to hear it. That is the problem that i am having right now. I have tried several different converters but to no avail non of them have helped in the situation. So currently I am stuck. I have searched the internet and forums for answers to my problem ┬ábut non of them have seemed to work. Please Help….
