I have a very large library of movies in my itunes library. They were all ripped using the ATV setting in Handbrake. Works fine (when my atvs are working that is). I had a gift certificate to best buy and wanted to get something for my daughter's room to just put a bunch of her movies on, but didn't want to drop the full price for another ATV (also the wireless signal in her room is bad). So I bought one of the Western Digital Media players, knowing that Best Buy is pretty good about returns even with opened packages and if I couldn't get it to work to my satisfaction then I could always bring it back. Visually and speed wise it seems to work fine, but as someone had pointed out, since my movies are all .m4v extension encoded for Apple TV then on the WD player they show up as having no audio track. Is there any quick (or not ridiculously slow) way to take about 2 dozen of those files and convert them all at once to a format that would work? I'm guessing just basic .avi or whatever else might work. If not and I'm looking at having to re-rip every single one of her movies for this then I'm going to return it and not bother. But if there's an easier way than re-doing every movie through handbrake then I'll try it. Thanks in advance.
