How can I play a movie file with a .dsm extension?
DSM is another kind of video container. To synchronize/sync dsm file, it is better to output wmv format first. If you want to output dsm file, please download DSM Muxer, unzip it with WinRAR. register it with the command line "regsvr32 DSMSplitter.ax" and "regsvr32 DSMMuxer.ax". Select DSM Muxer, rename the output file extension as *.dsm. Select other options like avi format, you can get dsm file. But the muxer is not stable.
try to avi?
