I have only recently bought a BD-RW drive but as of yet have not actually burned any movies to a Blu-Ray disc. I was able to do everything with DVD discs, such as authoring with VOBs and burning images etc but I am at a loss of what to do with a MKV file. I have PowerProducer software that I got with my drive but it will only allow the input of VOB files and a couple of other formats but I'm not sure what to use to convert the MKV. I also don't want to lose any quality from the file when converting. Really hope someone can help as have trawled so many threads and posts lookign for an answer but have yet to get anything to work. Thanks for reading.
