Hey guys i just picked up a Sony walkman NWZ-A728B the other day and i want to convert some videos to put onto it, but the only formats that works with it are MPEG4 and AVC. I have never herd of AVC so i dont know if that ones real or not XD, most of my videos are in AVI format or WMA. So if any one knows of a converter that works that would be great, allso if the converter can lower its file size that would be awsome. Thanks guys for your help
