我用growisofs刻了一张DVD growisofs -dvd-compat -Z /dev/scd0=image -speed=4
刻录过程没有出现错误，但使用时出现了问题。 盘上的一部文件可以读取，md5sum校验无误， 但用MPlayer播放其中一些rmvb文件时，整个屏幕变花，但音频正常。 我把这些文件复制到硬盘后再播放就正常了。 读取另一些文件时，出现 Input/output error。 刻录机型号：BENQ DW1640 ，用USB外接。 请问如何解决此问题？谢谢。 下面是dmesg的输出： sr 0:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK sr 0:0:0:0: [sr0] Sense Key : Medium Error [current] sr 0:0:0:0: [sr0] Add.
