Thanks for the info.
Here's a couple more odd things. Using just the DLNA ability of the new PanasonicTV alone it can access MP3 files, play them through my A/V receiver, also can see and play JPEG files seperately or as a slide show and and just as a test I moved a dozen MPEG-2 files and a few MPEG-4 files to a folder and they played on the tv just fine WITHOUT using MC.
Now I can open the the same files in MC from my PC and the JPEG's play fine, as di the same MPEG-2 and MPEG 4 videos. Guess what, accessing the same video files linked to MC, using the TV it shows the thumbnails, but refuses to open and play any of them. There's a ! on top of folder icon, but only when accessed off the TV. What explains their weird behavior?
It for sure isn't the TV, because I hooked up WD's WD TV and the same files play fine, as they do accessing them using a Asus Transformer tablet, using it file access utility and also multiple apps. Why can't MC play everyday MPEG-2 or MPEG-4 files off the TV?
