Can you select MainConcept MPEG-2 in the render dialog? If not a broken or not properly installed MPEG plugin could be the reason.

yes

It is M2TS file from sony cam HDR-SR11
Vegas 7.0d does not even see that file!?

7d is not designed to work with avchd files. It is 7e and up... but 7e was the first version to work with M2TS so it isn't very good. If you're working with avchd (M2TS) then you really should be using the latest version...8c

Download the trial version of Vegas Pro 8.0c and use that until Vegas Pro 9 comes out.

The trial versiojn only works for one month and I'm pretty sure that won't be long enough.

The trial version is also missing AC3 encoder, DVDa.... and the biggy.... mpeg encoder. You can't import/export avchd or mpeg of any kind. All you can do is play with avi

This was in former times. The current trial versions are fully functional and only time ristricted. You can use and export any type of media just as in the full version.

This is another one of those problems that used to absolutely drive me nuts and that isn't at all what it looks like.

Here is your problem. You are capturing your HDV (m2t) video with your virus checker enabled, and possibly some other background apps stealing CPU cycles as well. What is happening is that the virus checker (and possibly the other background applications) are occasionally stealing focus from the capture utility during the capture and introducing small errors into the captured clips.

Vegas 7d and earlier had extra error correction which could handle these errors, but did this at the expense of previewing efficiency. Later versions of Vegas dropped some of this error correction which improved previewing efficiency, but introduced a new problem which unfortunately as you are now seeing is quite severe: that these errors will now crash Vegas.

The solution that many on this forum have used is to go back to the older version (7d) of Vegas that uses the less efficient but more robust method to play back m2t video.

The method that I would recommend instead is that you recapture your video but this time turn off your virus protection and any other background applications you can see (by calling up the Windows task manager by pressing control-alt-delete) before you capture. I also turn off the video preview and screen saver and don't so much as even jiggle the mouse during capture.

Anyway, doing this has eliminated my problems of Vegas crashing on m2t clips almost entirely. I still occasionally get a clip with errors, but it is very rare now. When I do get one of these occasional errors, I just convert that particular clip to Cineform codec avi.

Another solution is to use a tapeless solution like the Sony Z7 or S270 which use CF cards instead of tape. This will give you error free m2t video as long as you use a fast enough CF card.

Also keep in mind that not fixing the HDV capture problem but simply working around it by using Vegas 7d passes these errors on into any m2t master that is smart-rendered. This can be an issue if you try to play the master back using Windows media player (where it will likely crash) or if you use this m2t render for creating a Blu-ray disk (which is very likely to glitch or freeze playback in a typical Blu-ray player).

At one time I thought that this was a tape quality issue since Sony does sell higher quality HDV rated tapes. Experimentation has lead me to believe that this is not the case however. When I switched to the higher quality tapes, I got just as many errors in my captures. It wasn't until I started turning off the virus checking that I started to get error free HDV (m2t) captures. Now I am back to using standard Sony Mini DV tapes and everything is fine.
