Media Player Classic video size zoom incorrect

I'm running VLC v1.1.8

1. Go to Media
2. Click Open Capture Device
3. In the capture mode dropdown (where it says DirectShow by default), select Desktop

The show more options checkbox will allow you to adjust extra functions

Next click the dropdown arrow next too play and select convert

This will allow you to select the file save location (remember to add the file container e.g MP4) preform a test run in case you are unsure which file container you require.

Next select the settings you require from the drop down box you can edit them as required.

When you select convert the vlc screen will black out and recording will begin. Please note there is no audio capture (at least not in the settings I used)

Press stop to finish recording

Edit: Updated too add notes from my comment for an easier read

MP4 is just a file format. It describes how data is packed into a file, but doesn't tell you how it's been compressed. Your file uses video codec that is supported by your players and an audio codec which is not. Your players can't decode sound. That's also the reason why you don't hear sound after splitting the file - the program you used didn't support that codec, so it has just ommited sound entirely.

As @BrunoPereira suggested in the comments, you can use MediaInfo to get some details about the codec used.
