Sounds like it's truggling to read the disc or a power issue. Ensure you have connected both cables and also use either ports directly off the motherboard (not case ports) or a powered USB hub with at least 24W.

Also, try cleaning the disc with a microfiber cloth. It may help and costs nothing!

No improvement from cleaning and trying various ports and hubs sadly. The Buffalo does appear to have a 5v dc barrel jack which can be used instead of a second USB I am guessing? I could get an adapter for a try. I just bought the disc so I could also return it.

Fixed! You seem to have been correct with the power issues idea. I tried the USB hub built into my monitor as a long shot and, although the console did spit out some AV sync errors, it did produce the MKV files. They play back perfect. Thanks!
