I just downloaded one post (NZBID 2943270)
I faced TWO problem :

-----------1----------
Problem is that there is ONE wrong par2 file included in the report (it's episode 10, not 9).
SABnzbd just tries to download this particular PAR2 file, and thus fails to verify/unrar (i enabled the option to stop processing if par2 fails).
SAB should be smarter, and download all the par2 index files (not the verification blocks, just the index files), and then check the archive with all of these par2 index files ! (in this case, the report contains PAR2 index for episode 9 and 10, and more than enough episode 10 blocks to repair it without any problem !)
Funny thing is that these rar had 0 problem, but the whole thing seemed to have completely failed at first.
I had to download par2 files separately (because SAB did not download any), and check manually.
-----------2----------
To check that faster, I tried to download only the episode 10 par2 index file (no repair blocks)
Downloadind that single file failed with this error message (the queued item would stay indefinitely0 - using Mac OSX, SVN from yesterday night, python 2.5.1

To finally solve that whole problem, I had to download the whole par2 set fr episode 10, which finally worked.
-----------------
Request : FAILED downloads should be in a FAILED directory. Because in that case, as I am using TV show sorting season folders, No folders, The whole RAR set + the wrong episode 9 par2 index file landed in the middle of my other episodes ...
-----------------
Do you guys mind have a look at those two bugs ?
Thanks,
