Every time I run TMPGEnc it seems to get slower and slower. A regular 90 min. movie would usually take me 4 hours, now its taking me 16 hours!! My hard drive is fully defragmented and TMPGEnc is the only thing running on my computer when I encode. I am running on a P-4 1.3 Ghz 1.12 GB of RAM and a 40 GB Hard drive. Can I do anything to speed up TMPGEnc??
