ivtv初期化しないとうまく動かなくなるらしい。

ivtvが動かなくなったというか、mplayerでTV表示できなくなった件、一応解決したので書いておきます。
/etc/rc.d/rc.local にこのようなコマンドを書いておくと治りました。

# GV-MV-RX ドライバ組込み init

modprobe ivtv

sleep 2
# TV映像サイズを720x480に設定 サイズはなんでもいいらしい

/usr/local/bin/ivtvctl --set-format=width=720,height=480
# チューナーを日本 チャンネルを2chに

/usr/local/bin/ivtv-tune -t japan-bcast -c2

このあと、これでTV表示可能。
mplayer /dev/video

肝心なMythTVはやっぱりエラー出て動いてくれない
時間?がとれてないのが気になる
