Recently I've been having a to wait for about 30 seconds before a video file opens either with Windows Media Player, VLC Player, or Media Player Classic.

Each time I try to open a video the progress bar starts and it stays there for almost a 40 seconds (screenshot: http://i.imgur.com/zavqBNO.jpg) until it stops then the video file opens.

It happens with all formats I have: mp4, avi, flv, mpeg.

I have Ad-Aware Antivirus running and it detected no problems on my machine. I would like to solve this without having to reinstall Windows.

PD: I have a very fast machine and the videos are on a new Samsung SSD, so I don't think that's the root of the problem

  • My first thought is if the SSD is using the current firmware revision. The second is you will need to benchmark the file access to verify if this is a codec problem or a file read access problem. These are non-network files? The fact this happens on several different programs and video container formats indicates a file access problem honestly. – Ramhound Jan 9 '14 at 16:51
  • The video files aren't on a network location, they're on my PC and my SSD has the latest firmware. – KurtWeddle Jan 9 '14 at 16:58
  • Time to run a benchmark on your SSD to confirm its working to its specifications. – Ramhound Jan 9 '14 at 17:08
  • It is, even better than with factory defaults. Only video files seem to be affected – KurtWeddle Jan 9 '14 at 17:09
  • My only suggestion would be to use a Live Linux disk, use VLC, and see if the problem exists. This will now confirm if its a codec problem. – Ramhound Jan 9 '14 at 17:19

As you confirmed: the virus protection must scan the file. If this is a feature-length video, then it is probably in the GB size range and the file takes a noticeable amount of time to be scanned, or you can attempt to whitelist a folder into which you place pre-scanned files to avoid the scanning delay.

  • I don't think my current antivirus has that option. I can only disable real-time protection. – KurtWeddle Jan 9 '14 at 22:12
  • Ad aware? Check under "scans" settings for an exclusion list. AFAIK, this list is honored for real-time scanning as well as scheduled scans. – horatio Jan 9 '14 at 22:17
