i THINK (not know but think) that there is a temp folder for newtella somewhere and if you find it then you could listen to the incomplete file via winamp or another program. as for bitrate and stuff i would reccomend db power amp. i'm to lazy to find it's site right now but i'll tell you, you can go to www.downloads.com and search for it and it will be there. it's explorer intigrated and is primarily a converter but it also comes up with a little info box that gives stats when you hold your mouse over a supported file type.

hope this helps
