Problem Burning A VCD Using Nero 7

According to pcmag.com the best disc burning software were the following:
1. Ashampoo
2. Cyberlink
3. Imgburn
4. NCH Express Burn Plus Video
5. Nero Burning ROM 11

I thought Nero was the best software ever for burning audio and video. With the previous version of Nero, I was accustomed of burning more audio and VCD's as well. With this article, it featured out that Nero is on the 5th list among the best software based on 2012 review. While according to the latest review Nero was on the 6th list where I believe have been trusted and used by many. 

Using Nero 7, burning a video using an MP4 format does not show any problem. It went through well while transcoding and burning it onto a CD. And when I check the output, the video and audio are intact. 

First, I tried to burn using the original format and it turns out that no audio appears in the output from the start  to end of the video. The original video has .vob extension name so I converted this to .wmv hoping it may work this way. The conversion is completed with video and audio track on it.

Then, tried the second time using the converted video. It tooks 30 mins of transcoding and smoothly goes fine and successfully burned. But when I try to check the output, it appears that it has sound in the first 2 seconds and the rest of the video has no sound which is different from my first attempt.

This puzzled me and afraid of burning another copy which may result to wasting few blank cd's added to the ones I already burned. I don't know what went wrong while burning a .VOB or .WMV format video using nero 7. 

I'm not sure either the problem is the CD writer or the computer itself. But the CD writer is a month old brand new Samsung DVD multi-recorder. This is the first time I used it to burn videos. 

The previous version of Nero installed in my computer was quiet doing well in terms of audio and video burning. But this Nero 7 does not do well.
