i have been using sms since june and it has always been a great application. i would vouch for a autoload functionality so that when the cd/dvd is loaded the predefined movie starts automatically (and further some form of playlist like functionality). Which I guess will be relatively easy to implement.
By the way, ver. 1.3 was able to detect my memorex 1gb thumbdrive with gt3 usbd.irx. but the later versions do not(I tried a whole lot of usbd including naplink's). If it a minor fix in code, please direct me on, were to look for in source code to fix this.
