DVDStyler V1.8.4.2 consistently freezes at same point

right,

On my old laptop (HP Pavilion ZV5000) I used DVDStyler a fair amount to burn DVDs that would look nice with a DVD player. However, I just installed DVDStyler (latest version from site) onto my new machine (vastly higher specs) and it keeps freezing.

The DVD I'm trying to burn contains:
-Two menu pages (main and video selection), both with customized backgrounds and both with MP3 files in the background)
-Three video files (yes, they do fit size-wise) (I removed one after the second failure, still freezes)

It seems to go through all the frames the first time, but then when it gets onto a second section entitled 'stream mapping', it becomes inactive, and when I click on the window, it changes to 'not responding' (CPU usage also drops to 0 for the DVDStyler process when it gets to this second stage). I would paste the text, but of course I can't as the window is inactive, so I'm afraid a screenshot will have to do

(no, the screenshot doesn't say not responding on the title bar, only because I haven't clicked on it yet this time, but I assure you it isn't doing anything)

I just went looking around for an older version of DVDStyler and downloaded and installed it (I went for the final 2010 version, as I knew that worked on the laptop), tried burning the disc again and it worked. Guess it must just be an issue with the latest version then.
