kernelの再構築で
kernel-2.6.31/linux-2.6.31/drivers/media/video/ivtv/ivtv-i2c.cの
640行目あたりの

kernel-2.6.31/linux-2.6.31/drivers/media/video/ivtv/ivtv-i2c.c

const unsigned short addr_list [] ={
    0x1a,  /*  Hauppauge IR external    */
    0x18,  /*  Hauppauge IR internal     */
    0x71   /*  Hauppauge IR (PVR150) */

の

0x1a, をコメントアウト　-> //0x1a

その後再構築すること…8時間。。。。
再構築されたkernelをインストールし、
grubで　2.6.31.6-166を選択（構築したカーネル）

何も設定せずにいきなり
mplayer /dev/video0
