question on Mareix Rev Combinations

Magic -> Matrix Rev CAM

Hello, this is my first post to this BBS although I am not a complete newbie.

I have recently upgraded my Magic cam from Matrix Rev 2.19 to 2.21.
Inserting this into the Technomate 5500CI, I see it recognises the new CAM. However when I reboot it into an FTA channel then go to other channels like T*S and TV C*bo, I can seem to clear the channel. Does anyone else get this problem?

I used to use Titcard with Magic (converted to Matrix or something like that). Can a blueTit card still be used in combination with Matrix Rev?
