本人装了”TMPGEnc.DVD.Author.Pro.2.1.5.77“后，试下打开岩岩用TMPGEnc PLUS 2.54转换好的MPEG-1 格式的文件时就弹出一个错误框，内容是： m",G;VN  
“This file cannot be processed by using smart rendering. .p(r|5(b  
l0tFj>q"  
Could not find the necessary information to process this file with smart rendering. R#s_pW{op  
*E-MJCv  
It is possibly an MPEG-1 with a variable bitrate. This format does not contain the maximum bitrate information needed for the smart render function.” 8tzL .P^
