Comment 3 for bug 515600

The inability to seek in some players is due to Sound Juicer not generating seektables. You can run a script that will correct files that you've already ripped (attached). Just execute it in the root of a directory containing a lot of flac files; it recursively searches and adds seektables.

Of course, the ideal solution would be to integrate seektable generation into the actual creation of the flac file.
