Today, I downloaded MPlayer-1.0pre6a.tar.bz2 just started learning Linux, I was not familiar with many commands, so I encountered a compressed package, I was a noisy TAR ZXVF, but the system prompt error finally found a solution, under TAR XVFJ MPlayer -1.0pre6a.tar.bz2 You can see that BZ2 has become .tar, mplayer-1.0pre6a.ta then you can successfully install it!
