I tried opening serveral wmv files to see what the frame rate of the files were but I keep getting an error that says Couldn't locate decompressor for format WMV2 so does anyone know a way to open these files like what codec I need or is there any other way to check the frame rate besides virtual dub? Finally do I still need to be able to open the files with virtual dub to extract the audio or is no extraction of the audio needed for WMV files?

Please help and thanks in advance.
