Oh really? do you know if there is a way to increase the priority to the CPU or is it automatically governed. At the moment, a 6hr recording is taking my G4 500mhz about 6 hours to convert in to an mp3. I mean, I don't mind, because I'm using my machine for other things while it's converting in the background. But it would be nice if it was possible to chuck more CPU time at it.
Also where can I find the latest version of PPCMC?
The Macintosh Garden page linked in the original PPCMC 7.x MacRumors thread will always have the current version.
PPCMC is using the all of your CPU, Mac OS X isn’t Windows were you can set priority. All of that is automatically handled. Any file converting will happen much faster if it is the only thing the machine is doing. Any other simultaneous heavy tasks will slow it down possibly significantly, light tasks should not affect it that much.
Having a 500MHZ CPU doing conversion with the latest FFMPEG release (which is what PPCMC uses) + heavy tasks at the same time is why your experiencing this. I don’t even bother converting anything on my 300MHZ G3.
The next version of PPCMC will have a special G4/G5 download with AltiVec optimizations on in FFMPEG, alongside the standard G3/G4/G5 version. This will allow your G4 to use AltiVec code which allows for faster file conversions.
