I trying to convert a .mkv 1080p movie using mkv2vob through the USB method. I usually stream these files using Tversity, but I would rather put 1 on my 16gig usb drive. My issue is when i convert the file properly (including converting from DTS to AC3) when i plug in the usb to my ps3, the picture only shows half screen. It is as though the image has been moved to the top of my tv screen (almost looks cropped). Any one know a fix to this? again, im using the usb option in mkv2vob and the only issue is that the picture is cropped when i play this on my ps3. Solutions???
