But Isee in the AMV Tool 4.00 there is 88k,

But i dont understand why, then it is a very week video file. MP3-s perfect, then I dont understand why arent the sellers, the programmers make a format with good audio quality possibility. (min 44K, 128 kbs). I think it i a big trap. I purchased the player MP4 digital player....
But it wont play mp4, which has a good audio quality, then plays amv, with reduced audio. And there is no possibility to convert tha same video file (WITH HIGH QUALITY SOUND) to amv with the minimum requaired audio standard 128 kbs. There is the option in settings, but it greyed, so it cannot change. And I think this is direct! I will buy somthing better in the future, a sony, or other wich realy can play mp4. I tried what you said PocketDvixEnc. but the amv is louder, but the sound the quality of this soundwave is bad, its not clear becuse of the reduced KH. I dont know what to do, There isnt any possibility to get a cracked AMV Tool from somwhere, in which this option is not greyd?

Thank You for Your kindness, and for the quick answer.
