MP4 Files with no sound

I recently purchased a new phone (as my old one died), rather than going for a "normal" mobile I decided to go for a Windows smart phone. The main selling point was the features which allow me to store my whole MP3 collection and listen to them via the pre installed Windows Media Player, take photos and videos, surf the net, send e-mail, use as a modem and err oh yeah, make phone calls (basically may devices in one). Anyway, enough of all that, one of the main problems was when I transferred video files created on the phone to my computer for burning to VCD, etc the sound seemed to vanish with my PC's media player throwing out errors at me. My first thought was to go a googling thinking I would find a solution in no time whatsoever, the results soon displayed that even more people were shouting the same words "Where's My Sound Gone!" This common problem also seemed to affect other models such as XDA's and most other phones that record with the MP4 format. After reading a few forums it seemed likely the issue was caused in part by the phone companies, this is because the MP4 file was using a sound format that is normally associated with the 3GP file format, this is all fine and dandy but my files still have no sound. Many downloads later and a shed load of Ad/Spyware I eventually found something called the "Mpegable Decoder", well I say found... a working download was somewhat elusive to say the least. Anyway after a quick install the codec was applied and Huston, we sound :o) BTW: As I am generally a nice chap (although lacking on grey matter for getting this stressed over an MP4), I have added the setup file to my own web space just in case you were looking for it. Downloa d the Mpegable Decoder here (Adware/Spyware FREE).
