Is anybody using PS3MS in OSX? My mac is having a hard time transcoding HD mkv content. I have to enable multicore support (sometimes unstable) and yet it manages it by a thin hair. Since the buffer runs out, it might be a CPU thing. I thought that nowadays even low end CPUs have no problem dealing with this. This is an 2008 imac with a 2.4G Core 2 Duo, using Subjunk build.
