So maybe encoding to a anamorphic size doesn't matter all that much anymore with latest hardware players/ computers? The media tank I use seems to be able to handle the high resolutions that he talks about, so I wouldn't need a anamorphic encoding....

Yeah, but if you're encoding from an anamorphic source, then you have to resize the video to make it the correct AR with square pixels, so you have to either have lower resolution (bad because it's lower resolution ;-) ) or higher resolution (bad because you need more bitrate while you don't gain any additional detail).
