When h.264 HW support comes, do you think you will make a GUI that will cater for that conversion? I know earlier in the thread someone suggested it and said it would be good to keep that seperate from avi.NET (and I agree). If you read
this post you'll see that you already have most of the requirements in avi.NET to make such a GUI. Just send the avs script to x264.exe instead of avs2avi and use a different muxer...
