Notable Fixes/Changes in Version 6.0d
Support for VR-mode DVD Handycam® camcorder discs has been improved. When importing video from Sony DVD Handycam discs in VR or Video mode, each chapter is now imported as a separate file.
The MainConcept AVC/AAC codec has been added to Vegas. You can use this plug-in to import H.264 video in your projects and to render H.264 video (including support for HD frame sizes, two-pass encoding, main and baseline profiles, export to all common frame rates— including NTSC, PAL, and 24p— and Apple iPod® video format).

Please continue to use the Sony AVC/AAC encoder to create video for the PSP™ (PlayStation®Portable).

Video quality has been improved for the Sony AVC/AAC encoder and rendering templates have been refined.
A problem has been fixed that could cause problems when reading AVI files with MP3-encoded audio.
A bug has been fixed that could cause Vegas to hang in some low-memory situations.
A bug has been fixed that could cause Vegas to crash after copying and pasting Bézier mask keyframes between events.
A bug has been fixed that could cause Vegas to crash when pressing Alt+Shift+4 to toggle external monitor preview when the Video Preview window is not visible.
A problem has been fixed that could cause nested projects to display the incorrect length.
Audio/video synchronization has been improved when reading certain QuickTime files.
High-definition Windows Media Video rendering templates now use the Windows Media Audio 9 codec for improved device compatibility.
