Premiere Elements high CPU% burning

I just bought an LG DVD burner and everything appears to be working well. I can burn a data DVD with Nero and do about 4 gb in 6 minutes. So, I know it's working okay.

When I try to burn a 53 minute DVD with Adobe Premiere Elements (home videos), I encounter problems. Basically, when its encoding the data (the first step) it says the time remaining is around 4-5 hours. Does this seem right?

Also, the CPU% goes really high. I tried burning it last night before I went to bed and when I woke up I had a virtual memory error. It looked like about 75% along the way it stopped with the error.

Now, I've been searching around reading about VM, etc. and I've tried a few things:
* expanding my VM
* closing down programs in the background both manually and with msconfig (all non-windows programs) then retried it
* defragged HD
* my hard disk has 10 gb remaining so that shouldn't be an issue.

I'm thinking that maybe its the Adobe program. Any ideas on how I can get this thing to encode/burn faster?

Although I think it might be normal -- it could probably also be a memory leak in the software itself.
