JRISKIN  I combed through the periodic scripts and found NOTHING related to memory.

The weekly runs the following scripts, 310.locate (update the spotlight database), 320.whatis (rebuild the manpage database), 999.local.

I can't imagine how this is optimizing memory except that things are going to shift around while it rebuilds databases.

JRISKIN  Had some .FLAC files, wanted .MP3/.M4A (aac)...

Worked quickly and easily. Lots of options.  
(Version 0.8.1)

JRISKIN  3.7 is supposed to support the Pentax K10D. I tried both the plug and the converter and its corrupting the data passed about 65% of the file. Tried several files, same results. All in PEF format. I already switched to DNG (which works fine with or without this update), but I have some PEF's I took right when I got my camera and I was hoping to update them to DNG.  
(Version 3.7)

JRISKIN  The ONLY negative to this, is that if you need it for MPEG2 (which it handles amazingly) you need the quicktime MPEG2 codec.

Other than that this is the stuff...I just can't say enough good things about this product. In a much earlier version I noticed a small capability it was missing and emailed the author who promptly updated it in the next update.

Love it.
