DVDFab platinum performance

Hi, I installed last version on powerful computer Core2 Quad + 4GB + SATA2 and started conversion of DVD to MP4 format. Then it took about 38 minutes to complete an 1 hour 20 minutes movie.

Meanwhile I monitored computer resources and seen that the process only used max 30% of processor, RAM was quite low and disk access was not very high. I think that there is more room for the tool to accomodate and that the processing time could be shortened.

Is there any explanation on this behaviour or any way to tune the performace?

I wonder if some easy performance gain could be achieved by spawning separate threads for each VOB? (upto the maximum number of CPU’s reported by the system) I believe having more threads than there are logical CPU’s will produce diminishing returns.

Just my $0.02
