I have seen a few junk cans around, but this one particular day my search resulted in every file being junked...But to my surprise some of the files I had already downloaded, watched and rated them on Bitzi as Best Version, so I knew they weren't junk..So I UNjunked them all,I then went ahead and downloaded my episode and it was perfect...I think someone must of junked them because they didn't like the series....
That's just one scenario...
This thread will show you what file sizes to be careful of...
