Welcome to the Rockbox Technical Forums!
The stkov error is a known problem, and appears to have started a few weeks ago on at least the H300 and H100 players.A workaround seems to be to create an empty text file in the .rockbox/rocks/ folder on your H300 called "mpegplayer.cfg".For those interested, this was discussed in IRC yesterday (19th June), starting at 21.22.37 in the logs.
