I am using 2.4.3 beta 3 on win 7 and have the latest update for my iPad from the app store. When I have played a video and then go and check the drive content that video file is missing from the iPad list. When I then check on the HD it is also missing from there. It doesn't always happen but it is getting more frequent. My HD is shared from my router port so all connect PC on my home network can access the folders/files on it. The air video server is pointed at the video folder on the HD. Notably I had a folder under the video folder which had many family videos after playing some of these they were then deleted from the HD luckily I had backups.
Any help appreciated.
