The Adaptec AVC-3610 USB tuner does not work with TV Server. The graph is built and runs correctly, however audio is not detected. It looks like this problem has been around for quite some time. See the links in additional information...

h4. Steps to Reproduce
1. Install and connect an Adaptec 3610.
2. Scan for channels in TV Server.
3. (Channels should be found without any problem as long as the tuner is connected and set up properly.)
4. Attempt to timeshift or record any of the channels found in step 3.
5. (Fail: no audio/video detected.)
