Hi, all. First post here. Looked around for an answer to my question, but was a little confused. If this is in another thread, I apologize and this post can be merged there. I am slated to receive my Vizio Co-Star today. At the moment, we play .avi and .mp4 files through Windows Media Player on a laptop and stream it through the PC port on the TV. Most movies and TV shows are stored on an external HD. With the Co-Star, we'd like to play these files through the Co-Star as we would our laptops. I've seen a lot about Plex here, but our computers at home are work computers, so we can't add the software. The laptop we use for downloading files is an archaic G4 only running 10.4.11, so Plex can't be added. Is there an app to download to the Co-Star which can play these files? Is it like a Mac OS or Windows manner of just seeing the device as plugged in where we open the device, see the files inside and open them to play? The most dummy-proof, simple manner would be most preferred for myself and my even-less-than-me non-tech-savvy fiancee. Thanks in advance.
