I think you're going to have a problem watching online video "live" (besides, the bandwidth just usually isn't there). However, if the video file is available for download, and in a compatible format, this is, Windows Media or another format that the DSM-750 can decode, then you will be able to stream it form the PC to your television. The tricky thing is making sure that the file is in the appropriate format. I hope that D-Link will improve and expand the types of files the 750 can handle.
