I've 2 Terratec S7 tuners. Both is working. I've tested them one by one. I'm only able to record on program at the same time. If I'm watching a live program and a recording start, my live program freeze. If a recording takes place and a new one starts than I end up with many small file pies for the new recording. They are useless. In the web configuration I can see the status of the 2 two tuners. Everything seems okay. Any suggestion
