Read it properly. It wasn't about OEMs bundling PoweDVD, it was about OEMs licensing a version of a Windows SKU that didn't usually include the DVD codecs with the codecs. Why they can't says something similar to OEMs with Win8 is beyond me:
"If you're selling a PC with a DVD drive pay an extra $2 and we'll include the DVD codecs with Windows".
Yes, by bundling third party software OEM sold machines will still play DVDs, but I don't see how that's better than paying $2 extra for it to be included in Windows. That's just more software to confuse people, go wrong, get out of date and be sub-par.
And I'm really not sure the saved $2 is likely to result in a cheaper OS. At best it will result in the inclusion or development of something else. And if Windows is $2 cheaper than it would be otherwise that kind of figure is so low wrt. the cost of a PC that it will just get lost in all the other costs and line the pockets of Dell/HP/Sony etc. when people buy preinstalled PCs (i.e how "normal users" get their copies of Windows).
