I have been using TMPGenc to convert asf and non-compliant mpeg files to VCD. I have several files that ran fine for a while (2%) and then slowed down almost to a halt. I checked the CPU usage and it showed the CPU was not very active (spikes of 30% to 50% every once in a while) but TMPGne is still working. When TMPGenc is working smoothly, the CPU usage is 100%. What is slowing it down? Any ideas??

Is there anything wrong with the files or TMPGenc (I believe mine is the latest version) or a combination of both? I have also tried to demux and remux and use ASFTool and other tools to repair the files with no improvement. What is wrong here? Should I cut the file into pieces and encode separately and then merge them? Please advise. Thanks.
