How do I view .wtv files in OS X?
How to watch a wtv file on a Mac without using VLC


Install WtvWatcher on the PC - this will convert all of your wtv files into dv-rms by changing the packaging, not be re-encoding, so it is really quick and deletes the useless wtv file.
Share your recorded folder with your Mac. I simple turned on sharing on my PC and then connected to it over SMB://192.168.x.x
Use Handbrake to convert the file to m4v, then add it to iTunes, or watch in in quicktime player or whatever takes your fancy.
