i've been told by Humax support that to transfer video files greater than 4Gb I need to format my 8Gb USB pen drive in EXT3. I can't find any reference to EXT3 in the Windows 7 help, so am wondering what to do. I have looked on the web and it seems to me that I need to partition my hard drive to install a different OS that supports EXT3 such as Linux. Is this a fact? Any advice appreciated but nothing too technical as I'm not exactly a whiz kid on computers!!
