1) Why don't my videos play any sound? And what happened to the volume slider that used to be there?
Your mute switch is on. Unmute your device, and you will see the volume slider reappear.
2) How do I convert video into an iPhone friendly format? (MP4, M4V or MOV)
It is left up to you to convert your videos into a format the iPhone can play. If you would like a suggestion, we really like Handbrake:
It is free, easy to use and can handle most kinds of video.
3) Why is iDiscrete stuck on the "Synchronizing" screen after using iTunes File Sharing to import content?
Loading lots of content at once via iTunes means that iDiscrete will take longer to load the next time you launch, as it is importing all your files into the app. Depending on the quantity and resolution of your content, iDiscrete might take a while to finish importing everything. In rare cases, iDiscrete may even crash during this procedure. If this occurs, please try relaunching the app until it can work through all the files, or remove the files that are still visible in iTunes and try again in smaller batches.
4) I'm getting connection errors when directing my web browser to the given URL for the iDiscrete File Manager. What gives?
First, a very simple check: Make sure your iPhone and computer are connected to the SAME Wi-Fi network, and that it is your personal home network (not your Wi-Fi at work, or a hotel, or from your neighbor across the street). Assuming this is the case, and you are still getting connection timeouts from your browser, 99% of the time a reboot of your iPhone and computer will clear up the problem. If it does not, try opening up port 8080 in your wireless router, and/or disabling your router's firewall.
