Karaoke on a Mac

I'm a mac person but use a pc laptop due to lack of karaoke software for macs. Also...ports on the new mac laptops are limited.
(I assume there are adapters to use a svideo connection?)

I just downloaded Kjams to try.

Here is what I use:

Sax & Dotty(winamp) and sometimes Virtual DJ.

I mainly use zip files to play karaoke at a show. (winzip or winrar)

I use MTU Microstudio to burn Karaoke discs to play if I got out and sing and a KJ only plays discs.

I use MP3+G TOOLZ (converts zip to bin...bin to zip, etc..)

With Sax & Dotty i use "Pacemaker" to change tempo, pitch, speed)

I also visit a karaoke room that uses MIRC client.

Are their mac versions of software for all of these programs?
