Mplayer problem

[david walcroft]

Found some extra information in the system log file I have no idea what 
it means

Nov 20 13:44:21 reddwarf kernel: UDF-fs INFO UDF 0.9.8.1 (2004/29/09) 
Mounting volume 'THE_DEVILS_BRIGADE', timestamp 2004/01/28 21:13 (1258)

Nov 20 13:46:02 reddwarf kernel: Buffer I/O error on device hdc, logical

Can some one tell me what it means please :-)
