This might sound like a stupid question but does tmpgenc use any certain codec to encode our dvd movies? I was wondering since I had read the following on the avisynth site about converttoyuy2

"You can also edit the registry to force your system to use Huffyuv as the system YUY2 codec. Look under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32 (the location will be different for Win9x). You should find a string named VIDC.YUY2; its value will vary according to your software and hardware configuration (for example, installation of an ATI All-In-Wonder Radeon set this to ATIVYUY.DLL). Change this to huffyuv.dll and Huffyuv will be called upon for YUY2 conversions. Encoding quality from an Avisynth script with TMPGEnc is much better with Huffyuv as the YUY2 decoder than with some other codecs; with ATIVYUY.DLL, for instance, subtle color variations became posterized. Acceptable results were possible with the ConvertToRGB filter, but this increased encoding time substantially as TMPGEnc needed to convert back to YUV as it encoded. Changing the system YUY2 codec to Huffyuv eliminates the expensive (and lossy) YUV->RGB->YUV conversion while maintaining the quality of the encoded output."

I did this and I finally got tmpgenc to read my avs script generated from downloaded avi's and adding ConvertToYUY2() after file source and before filters and they all worked, no errors :yippie: . I installed huffy and did the right click on install.bat and it never worked, I mean it installed but still got unsupported errors, and I came across this information last night and it worked, editing the registry that is. So after editing the registry and naming huffy as the codec will tmpgenc now use this codec or does it not use codecs to encode, or am I just being a .
