@T13, the following notification shows up: Advance INF Install Error can not find c:\windows\hfslip\hfslpxxx.inf *note: xxx denotes a number, see attached picture ...followed every instruction and reminder posted at the website, at first i thought the inf error was brought about by the codec files i included, since this was the first time i tried incorporating codecs (in HFSLIP\HFEXPERT\CODECS directory), so i deleted the folder ...but the same error comes out at T13. i have run hfslip succesfully before, the only difference now is i am using a Dell RTM xpcd instead of a VLK xpcd, does it make any difference? any ideas why i'm getting this kind of error now? 06_hfslip.rar
