Greetings. When attempting to scan the analog stations on my tuner card, the scan does not find any channels and the TV-Server Application becomes unresponsive. I need to stop the service and close the application in order to recover.

The attached tv.log and error.log show several instances of the following:
failed to add audio compressor. you must install a supported audio encoder!

I would think that an audio encoder is already installed, as the analog channels work with the FusionHDTV application.

Why is the Analog channel scan not finding any channels?
Is it because of the error message above?
If so, what is causing the error message?

Through another posts in the forum, I discovered that I should download and install WinDVR.

After downloading, installing and rebooting, I was able to successfully scan the Analog channels (See Screenshot 4).

Unfortunately, when I preview the stations, I get a blank preview window.

Why is there no video or audio in the preview window?

I have tried with both a hybrid card configuration and with out a hybrid card configuration.
Results are the same in both: No analog video or sounds in the preview window.
I have exported my channel lists, so each time I run a test I uninstall the TV Server and MS SQL DB, and then do a re-install.

I have found that by opening and closing the WinCinemaMgr.exe application, sometimes I can get the analog channels to appear. Unfortunately, I have also started to have problems tuning in ATSC channels, where I receive a "Preview Failed: UnabletoStartGraph" Error message (See Screenshot5).
