I've actually been having the exact same problems. .avi files work fine, but .wmv files don't convert. I was assuming that this was a problem with my mencoder or something, but maybe it's a vshare problem. I wonder if this has something to do with the new cronjob setting that was added in version 2.4. I haven't set cronjob and am still doing everything the same as before the 2.4 upgrade. Do I need to switch over to get everything working right?
