Used the AlphaCrypt Classic module with the latest firmware 3.19 in LCD Toshiba 37 XV635D in order from the cable television provider Unitymedia to encode the smart card UM02, the encrypted channels in Digital Basic package. The AlphaCrypt module with the decryption of digital private channels such as RTL, SAT 1, Pro 7, etc. problems. The private stations are retained after switching often dark can not be decrypted by the module, help since only one switch back and forth in the program channels, so that the station can be seen. Thought at first the Classic module would have a defect, but as here could read on Amazon and in other customer reviews and online forums, is the constellation of Toshiba XV 635D series (37 and 42 inch versions), AlphaCrypt Classic 3.19 Unitymedia SMARTCART UM02, not fully compatible and it hooks to decrypt the private channels. Have tried the menu from AlphaCrypt Classic, by changing the settings to be able to resolve the matter, unfortunately without success. Also, the reset to factory settings of the module, such as the customer service of AlphaCrypt recommended phone, has been unable to resolve the issue. If the stations are decrypted by the module, run the perfectly good in digital quality, you can do without an external receiver and requires only the remote control from the LCD. We can only hope that a new firmware possibly later the thing improved, so that the private channels can be seen every time you switch and need not be only switched back and forth.
