I have been making Blu-ray folders from video from my Canon HF100 (m2ts AVCHD) and noticed that the output is about twice as big as the file input. When analyzing the video it created I noticed that it had created MPEG-2 video at a bitrate of 25mbps.
I then used another Blu-ray creation software and it's folder size was as expected and upon analyzing the video it was in MPEG-4 (AVC) at bitrate of 15mbps.
Why is VideoStudio doubling my file size? Do they not have the codecs to compress as MPEG-4 (which seems silly since they decompress from the m2ts)?
Is there a way to get around this?
Blu-ray Size

Unless I'm reading this all wrong, your answer is right there in front of you. You are comparing Mpeg2 @25000 (made for REAL blu ray disks) and avchd @15000 (for avchd disks on dvd media).
Mpeg2 is quite naturally larger than avchd.
I've used quite a few programs now for doing avchd disks.... Pinnacle studio, Sony Vegas.... and a few others. By FAR the best program (IMO) for doing avchd disks is Ulead Movie Factory 6 (with the HD pack). If you're really serious about doing avchd disks then MF6 is what you want.

I thought that I read that Blu-ray disks/players accept both MPEG-2 and MPEG-4 (especially since the Blu-ray disk making software I used had their video streams as MPEG-4). It just bothers me that my original HD content is being doubled in size to become another type of HD content (which obviously can't be higher quality than the original).
Additionally my hang-up with just making AVCHD disks is that MF6 doesn't allow you to burn AVCHD disks as Folders (I'm largely done dealing with disks and like to have everything on hard drives)

You need to be careful with that. SOME blu ray players accept MPEG4 on home burned Blu Ray disk, some don't. Unlike the now dead HD DVD format, there is no real minimum set spec for blu ray players. It's a real mess right now (especially on the audio end of BD players) and you need to sit down and read the specs CAREFULLY on a machine that you plan on purchasing.
People normally burn mpeg2 on real BD disks since size is not really an issue. There is however no rule that says it has to be this way. MPEG4 can be used, so long as your machine can handle it. There is one other problem with mpeg4 and that is (to the best of my knowledge anyway) that it will not support AC3 audio. mpeg2 will, and of course avchd (the mpeg4 variant)
And yes.... sadly enough, it is true that MF6 will not allow folders
