what does     

 WARNING: skipping unknown sub-chunk 'fact'   

mean?

[sleepypedro]

it's probably just seeing metadata that it doesn't know what to do with.

i see a similar message when i feed it wav files that have soundforge markers or regions contained therein.

Correct.  it's just extra metadata junk in the header of the wav file that isn't really necessary.  If you're compressing tracked/mastered FLAC16 files, seeing *ANY* extra metadata that FLAC is ignorning means the WAV files weren't tracked using CD Wave, and may contain Sector Boundary Errors (SBE's).

thanks for the move brian, should have posted here in the first place.

i use goldwave, and have never seen the error before.  but, i've always tracked from the harddrive, not re-upped cd files of mine(external drive failed )  so, should i always have the box 'align on sector boundries' checked?

no john, i read in the flac pages that DO NOT do that, its pads them oddly

im sure mike will chime in tho, but i never do and havent had a problem that i know of yet

That was for older versions of the flac frontend... the current version of the frontend (which comes with installer version 1.1.0m, install the most recent one from my website just to be sure) will work with aligning sector boundaries just fine, given one caveat:

Make sure you have your files listed in the correct order in the Frontend!  This may seem simple, but it's the single largest potential for fuckup.  If the files are in the wrong order, it will align sector boundaries by carrying over extra samples to the next track, which isn't really the next track (if it's not in the correct order).  I'm not explaining it very good, please let me know if I should clarify and I'll explain it tonight when my head is more clear.

Sure, as long as you used CD wave, or some other sector boundary adherant means of setting track markers
