No Video 1) Make sure you are using the latest drivers for your video card.  Visit your card manufacturers website for details on how to do this.

2. No other applications are open that are displaying video.  The 'Overlay' may be used by another program preventing DNTV Live! to display the video, please close that application.

3. Make sure the channel you have selected contains video, it may be a Radio channel.

4. Change the Video Decoder.  Your system may not have that particular decoder installed or your computer isn't compatible with that particular decoder.

No Audio 1) Your speakers are connected properly and the cable is inserted into the correct plug.  Please check your Sound Card's manual if you are not sure.

2. Check that your speakers are not muted and are switched on.

3. Check the Windows Volume Control, by double clicking on the speaker icon in your system tray.  The audio may be muted or tuned down to low.

4. Change the Audio Decoder. Your system may not have that particular decoder installed or your computer isn't compatible with that particular decoder.

Stuttering 1. Your computer meets the minimum system requirements for DNTV Live!

2. Move the DVB-t card to a different PCI slot.  PCI slot 3 is recommended, however as different motherboards handle PCI slots differently, its hard to say which slot will work well for you.  Try each slot, you may have to move other installed cards around.

3. DXVA is enabled in the Video Decoder Settings

4. Change the Application Priority to 'High' (using the Windows Task Manager).

5. Change your monitor's refresh rate to a multiple of 25. 50hz, 75hz or 100hz.  To enable 50hz you need to use PowerStrip

6. You have a good clean signal.  Generally Signal Quality must be above 70% and Strength above 65%, these are an absolute minimum.  Reception may be achieved with lowers stats however choppy audio and glitchy video may occur.

7. Disable TimeShifting.  This will reduce the load on your computer, and may help reduce stuttering.

Picture Errors If you are seeing something similar to the example below or can notice strange picture artefacts, please ensure you have a decent antenna using Quad Shielded cabling.  Glitches in the picture are caused by poor antenna setup and/or DTV broadcasts being poor in your area .  Please Click Here to read the Reception Trouble-shooter.

No audio in FM Radio mode 1. Make sure you have plugged in the FM Radio audio cable from the DNTV Live! Pro card to your sound card or onboard sound solution.
