Well, Microsoft said a while ago there will be no more new Internet Explorer versions built. But things changed and now we are aware of the coming release of Internet Explorer 7. WM9 Bitrate Calculator 2.1 was released. For CCE/MPEG2/MPEG1 to WMV conversions, the need of setting the Audio Mode as CBR was necessary to avoid Encoder Errors on 2-pass. So from here on, the default Windows Media Profile will be created with CBR for Audio. Default video mode is still 2-pass VBR. It will also select Windows Media Audio 9 Professional codec by default for any Audio Mode you choose. Version 2.1 ======== 0088 == Final Release of WM9 Bitrate Calculator 0087 ++ File > Open Log 0086 =+ Code Optimization 0085 =+ Always choose WMA9PRO as default 0084 == Default Audio mode set to CBR 0083 ++ Fixed Resolution issue Please check the thread at MSUN Forums .
