Problem!Mp4 doesn't play all converted AMV

[MrJoe9090]

Hallo,
first my english isn't good because I'm from Germany.
Second:My Problem
I converted a wmv to amv and my Mp4-Player played it.
But when I connverted a mpg or an avi to amv my MP4-Player played the first seconds.The avi was a movie and the mpg was a music-clip.
My Mp4-Player is an Ipod clone with the following Firmware B002G2_V.1.6 Core 3.5.37
How can I make that my Player plays these movies.

MrJoe9090, Have you installed any codecs to your computer. You may not have all the decoding software you need to correctly convert mpg files. Download and install the K-Lite Mega Codec Pack from HERE, when you have it installed reboot then try another mpg conversion.
