HL Platinum to DVD help

[hunter444]

Hi, I just bought the platinum edition of HL which includes 5 games - HL, Opposing Force, CS, TFC, and Blue Shift. The problem is each comes on a single cd, and thus is a pain to switch in and out all the time. I am pretty sure that Blue Shift is the only game that still requires the cd to play after updating it, so I figured I could combine them into one nice DVD and then install off there.

My question is, how would I go about this? I know the installers are Wise, so should I attempt to setup a silent install? My only problem is knowing if all the updates that install along side the game would also install. I would like as little user interaction as possible, so that I can just click and it goes. My other idea was some type of advanced batch script. That way I could install the game, and then do all the updates in one install. Anyone got any tips? I am fairly familiar with slipstreaming things, if that helps.
