The file is an 'unknown format or damaged'.
I'm a bit new to all this. I've done it about 10 times without fail, so was quite surprised when mkv2vob had been handling rar files, and then threw a wobbly and said it couldn't unrar,.. It worked ok this morning with a 5Gb file, well actually it buggered up the sound, but it was ok 2nd time round clicking some dts to ac3 tab...
Anyone found a quick way of saving big files to the ps3? Wireless is painfully slow, and streaming can be a bit stuttery on my setup.
