No, ConvertXtoDVD is the fastest, in my opinion. I have used that and WINAvi and based on qulaity compared to speed, ConvertXtoDVD is better. So it's faster, considering the qulaity of video conversion you get. WinAVI might be a bit faster, but not as good of as converter.
I can convert & burn a DVD AVI (700mb) in one hour. Which takes longer? Burning with ConvertX or conmverting with ConvertX?
Well for burning check DMA is on See this... http://my.afterdawn.com/alkohol/blog_entry.cfm/231/dmaissues For converting speed issues, It's based on your PC specs. My PC also locks up (CPU 100%(ish)) when converting. Lol :-(
thats exactly what happens to my computer! what does the link show you? and is there anyway to let you actually let you use the computer? when converting videos?
