This has nothing to do with the aforementioned topic but it has a bit to do with the m2t bug that Michael N. mentioned here – First off, after upgraded to Vegas Pro 9, I discovered that it did not open project as fast as version 8, rendering also seems slower therefore I stick with version 8. Now, on to the problem with m2t bug – recently, I tried to open an older project which consists of multiple clips of m2t video, only audio came through but the video track was all black. Suspecting that version 8 as the culprit, I re-opened said project with version 9, same problem! I tried the same approach that helped fix my Vegas problem with Quicktime movies that I had in 2009: quit Vegas, uninstall QT, remove QT reg key, reboot PC, install QT version 7.6 (any later version would resurrect the Vegas m2t bug) – I could be wrong, but so far, Vegas Pro 8 is what I currently use and have no desire to touch Pro 9 albeit it’s considered an upgrade!
