I have...actually had a sony voice recorder. it recorded files in DVF format. At first i thought it was useless but was proven wrong. When you record lectures you often have to cut pieces out and recombine them. These tasks are a breeze with the Sony supplied software. It so happens that the Sony recorder stopped working and now I use an MP£ or a WAV recorder. These recorders are great but I have difficulty converting these files into DVF format. Am I the only one with this need? Thanks...http://nch.invisionzone.com/style\_emoticons/default/rolleyes.gif
