I am trying to prepare a Blue Ray disk but DVD Architect Studio 5 keeps crashing when it is 99% done rendering the audio (the video consists of 6 parts, 1 intro + 5 parts). Total file size: 29.1GB = 59% used.

I get the following error message:

In VideoStudio I have used the .m2ts format (Audio: 192 Kbps; 48.000 Hz; 24 Bit; Stereo; AC3 Video: 25 fps; 1920x1080 Upper field first; YUV; 16 Mbps
Pixel Aspect Ratio: 1,000)

I am using Windows Vista 64-bit with 8GB RAM.

I hope that you can help - thanks in advance.
