I recently start downloading Lead h.264 codec from site http://www.leadtools.com/evaldownloads/MM/Convert/LEADCaptureandConvert(eval).exe

I didn't finish download yet,so I don't know anything about that codec,yet.Can someone post some explanation of Lead h.264 codec,quality,speed of compression,etc.

Can this codec compare in quality with x264 and Nero Digital AVC codecs?

No idea - maybe try it yourself and let us know ;)

It seems to support non-standards compliant descrete wavelet transformation instead of DCT for H.264 codec.

The following LEAD codecs make use of wavelet compression: H.264, H.263, MJPEG2000 and MCMW

I recently tried out the Lead eval, none of their codecs are very good, (the ones that worked for me that is) and it installs about 50 directshow filters which I had to manually de-register becuase their uninstaler crashed on me I wouldn't have bothered but they were screwing up my yuy2 overlay and causing cpu usage spikes while using virtual vcr.

DCT is supported as well. I guess that their "Super Compression Mode" enables DWT.
