You can check out all the softwares and decide. My preference is MTU Hoster.
viewtopic.php?f=1&t=22248Most are designed for kj use, but many still use them at home as well.
MTU Microstudio can work as a basic player - no real hosting functions to speak of. Not sure which version you got, but the latest versions will actually send the lyrics to a 2nd screen. But as far as ripping programs, Microstudio is in the top 3 (#1 IMO). If you are having issues with Microstudio ripping poorly, either the disc itself is scratched to a point it can't be read or the DVD/CD drive isn't fully compatible.
There is also an ok free player from
www.karafun.com that will also play your ripped files.
Yes the mixer connects to the computer via USB - much better than using the headphone jack of the computer.
Again the wireless mics I linked to contradict the normal 'pick 2' rule. They are a good sound quality, don't feel cheap, not a lot of handling noise (like you normally get with cheap mics). Plus if one breaks, it's only $35 to replace. I took all my Shure SM58 wired & wireless mics out of service in favor of these GTD Audio cheapies. They sound 'almost' as good as the Shures and a little eq tweak, you can't beat em!
Speakers are probably the key you don't want to skimp on, those I linked to are actually 'cheap' for an ok sound. Yes you can get cheaper - but you really do get what you pay for in the end.
