Blu-Ray burn help needed

Hello, any help would be MUCH appreciated and I am even willing to repay anyone who can solve my issue. I currently use PowerDirector to make edits, final renders, and burns. But for a particular blu-ray project, PD will not burn any files to BD that are less than 4Mbps. A couple months ago I saw DVDA can burn to 720 SD files on blu-ray as low as 2Mbps!! Hooray! So I bought a Vegas bundle. Since my computer is a bit old and wouldnt work with the Vegas, I only installed DVDA (build 100) which is compatible with my system.

Here's my problem. Since the movie was created with my PD, I imported the video and audio as one file. I know this will cause DVDA to take longer to render/burn but thats fine. First I imported a M2TS file but in preview the video would stutter so I tried again but this time imported MPG2 and the preview played it fine. There is the main menu with 5 sub menus, that each have around 10 added chapter links. There is no animation in my entire menus. Only used JPGs as thumbnails for corresponding chapter links. Each menu screen, I added a short 20 second audio (.WAV) for the background.

So yes, theres over 50 menu links and all footage totals over 20hrs. All files equal 22.5GB at 2Mbps I want to put on a 25GB disc. Now I know what your all thinking, "your gonna end up with low quality crap at 2Mbps", but actually, they were originally compressed at that and play beautifully on my 55" TV. I know this project is abnormal, but because of this, don't mind if the burn process takes 5, 10, even 15 or more hours as long as the end result is fine.

I began the burn and after 16 hours it ended in error, "no space left on device". How is this possible??? My project is 22.5GB going on a 25GB disc and I have 74GB of available harddrive space!! How the heck would DVDA need more than 74GB of space to make this burn?!?!?!?!? Some of you may believe it is not possible to put 20hrs worth of video on a blu-ray disc but I have in possession another BD someone else made who accomplished this (and with animation in the menu) so I know it's possible. Just how can I do it with my DVDA??

It is possible you ran out of available space. My understanding is that twice the final size is required for preparation. This is because, even if the files are not recompressed, they are copied over and checked and then copied over to a disc image iso file. Twice 22.5 is 45 which leaves 49 gb free. Windows needs a certain amount of free space to operate so maybe doesn't let DVDA have the space it needs?

It is probably recompressing the menus to match the preset quality in the DVDA preferences. That could be expanding your project past the 22.5 GB. Burn to an ISO first and see how big the final file actually is.

Thank you both for responding. I just tried making only an ISO file and it ran out of disc space again. Apparently, DVDA will need more than free hard drive space 4 times the size of what your project size is to make either an ISO and/or burn. Seems i'll need 95GB of space or more for at least what im trying to do. Before I go buy an external hard drive now, does anyone know if I can create an ISO and do/or a burn but by DVDA doing the render/re-compression process on an external hardrive rather than your PC?

Options/Preferences and both the Burning and Mastering Tabs have provision for telling DVDA where to go. But I've not tried external drives so no guarantee it would work.
