[SOLVED] Sony SMP-N100 Not showing MP4 files

Hello Everyone! 
Normally I don't ask questions and I just google my way to an answer, but I seem to be having a difficult time with finding an answer for this, so please help if you can.
I have recently built myself a new computer and after installing Serviio things aren't working as they should and I can't figure out why. For some reason MP4 files are not playable now when they were before. Here are my system specs in case it is important.

Here are a few important things to note.
1. I am using a Sony SMP-N100 for testing, but I have other devices in the house that are having the same issue.
2. There is another computer in my household with Serviio installed and I have no problems playing MP4 files from it.
3. When I had it working before I was using Window 7 Professional 32-bit and now I'm using Windows 7 Professional 64-bit.
4. I have tried installing Java 7u17 64-bit only then installing Serviio, no luck.
5. I have tried installing Java 7u17 64-bit then 32-bit and then installing Serviio, no luck.
6. Absolutely no MP4 files are showing, but the few AVI files I have are showing, but with an * before the filename.
7. I am using the EXACT same settings as I was when everything worked fine. I used screenshots to ensure that.
8. I am using Serviio 1.2 where before I was using the last version.
9. I am using the same codec pack that I was using before except that I have some 64-bit codecs now as well.
Anyone have any ideas on how I can remedy this? Please help me and thank you in advance.
