Hello, first apologises if this question has been already been raised and answered. My WDTV HD Media Player (model WD00AVP) came with some example videos i.e. Nature, Snow Boarding and Surfing. These are .MP4 files so when recently I upgraded to a new Panasonic HD camcorder I thought I would take some footage, uploaded the video to .M2TS file format and then import them into Sony Vegas 9 and output a format 1920x1080 25fps .MP4 file. Hoping this would play via the WD TV HD Media Player just like the example footage, however I get the error message that the file cannot be played and to seek conversion. Rather than convert the .MP4 to another format is there something I need to be aware of regarding the "make movie" settings within Sony Vegas for a .MP4 file? Thanks, Travelbuddy (United Kingdom).
