:O my...my....front lawn!!! :'( haha ^_^ man, I take a few days out of playing MT to do some work and you go and blowup my garden lol
You mentioned that you wanted to get the farming mod but didn't want to install a modpack, why don't you just get Sapiers Farming Mod? its what I use on my single player world also you said you where having problems with Sapiers animals mod what errors did you get?
I'm running the latest fine on my side :S
With regards to recording multiple chat while recording you could look at using Mumble and Murmur (http://mumble.sourceforge.net/) which is free and open source. Mumble is the voice recording client and Murmur is the server that the client connects too ^_^.
I'll try and get on tonight after I get this current work I'm doing finished, do you think you could try and not blow up my house before then? haha :P
And finally another great video keep them coming :D
