I hated how slingplayer looked on my touch pro 2 so i edited a few files to make it look a little better, try them if you like, just download the .zip file, unzip the file then copy and paste the .gif files to the "Skin" folder in the sling media folder. By no means are these perfect but i thought i would share. If you want to go back to normal either Uninstall/install. or you can copy the "Skin" folder first then replace the files from your copied folder.
