[Igor Gofman] “I have the same issue. After rendering with my Vegas 9 pro (ver. 9.0e) it is impossible to play with any player. I have a media center Ultio MVIX that virtually plays any format. It plays M2TS file but it’s very choppy.
So, I render into M2T format and after that I convert the file into M2TS with 4UM2TS converter.
If you found the way how to fix it, let me know.”

I’ve had the same issue with Vegas Movie Studio HD and Vegas Pro 10 when rendering 1080i AVCHD. I came across this thread when googling the problem and the solution suggested earlier in the thread has worked for me – I ran the rendered file through tsMuxer ( https://www.smlabs.net/tsmuxer_en.html ) outputting it as an m2ts file.

Good luck with it.
