it works ok on my dads philips ** but the first time i tried it it blew the tele and he had to get a new one the screen just came up with "no common interface card" i had just learnt(or not )how to do a card and my dad trusted me(ha ha ) so they sent him a new card as my dad told them he had sent it with the tele.if your not careful the philips can lock out on the digital instal its a saftey system and you have to phone con d******l.so the real deal is get a gold card as you havnt got the worry of the tele system as well as the built in box with one and you can always blame your untouched original(hope that helps) <img src="wink.gif" border="0">
