Unable to add mp4 in Nero Vision

I am unable to add my mp4 files that I created using Nero Digital in Nero vision. It just says, "unable to insert ****.mp4".
Any advice?
Thanks.

 

Which version of Nero are you using, open StartSmart, go to Info Tools and locate full version

 

Nero Vision - 4.5.0.15
Nero Recode - 2.3.0.8

 

The version I am looking for is something like 7.0.0.0

 

Nero Burning ROM - 7.2.0.3. I have Nero 7 Premium.

 

Nero API version: 7.2.0.3 and 7.2.0.3b

These latest versions of Nero are full of bugs, I recommend you uninstall, run this clean tool http://ww2.nero.com/nero7/enu/Nero7_CleanTool.html and then install 7.0.8.2 a more stable version from here

I do not recommend 7.2.3.2b either(the latest version)

 

That did fix the Nero Vision problem, but now I have trouble with Nero Recode. Everytime I try to import a video, it crashes.

 

I take it that you are using Nero Recode to back up a DVD.

 

I am using it to compress videos that I have recorded using my PVR.

 

What error are you getting.

 

"Nero Recode 2 has encountered a problem and needs to close." Error report contains a reference to uldvda~1.ax. This is a mpeg decoder from Ulead?!
