I installed Twonky 4.4.5 on my Asus wl-700ge router and it works pretty fine (I am still evaluating it, probably I will buy!

These are AVC files and AAC music files.
The former are visible but it says "data not supported", while if I store them on a memory stick plugged to PS3 I can play without any problem. The latters are not displayed on PS3 ("no files" is displayed), while it seems Twonky correctly store them in its database as more than 1000 files are found.
Can someone help?
thanks in advance!
