Please note PCLinuxOS does not ship with Win32codes or DVD decryption software. Proprietary Nvidia and ATI drivers available after hard drive install.
libdvdcss2 and Win32 codec are in the repositories, its up to the individual to decide if they want these installed. Same with the GFX drivers.

Synaptic> Search> check install>

Also, as in Windows there's VLC player

Yeah that sound card problem is weird, anyhoo that TB Montego will sound better than the SB Live.....after you install the codec
