Ok problem solved!
I tried using compressor but the files where with separate audio or without it or the file extension wasnt supported…(im not very good with compressor)
The solution came with Visualhub,(im starting to love this program), using the mpeg preset without touching nothing but the quality to maximum it genereted a mpg1 file that plays smooth and with good quality.
I can say ive tried more than 50 combinations of formats, bitrates conversors and options and this is the only one that worked for me.
Hope this helps others! and thank you Daniel Low for the help and advice.
