I need to encode some ASN.1 Packets with Ethereal.


I assume you mean "decode".


ASN.1 is not recognized automatically by Ethereal.
As Ronnie Sahlberg notes, ASN.1 isn't a protocol, it's an encoding mechanism used by many protocols (just as XDR and DCE RPC NDR aren't protocols, they're encoding mechanisms used by protocols such as ONC RPC and DCE RPC, respectively).
Presumably the packets you're trying to decode use some protocol that uses ASN.1 encoding; if Ethereal already has a dissector for it, you should try using "Decode as..." to decode the packet as that protocol, and if it doesn't have a dissector for it, you'll have to write one and add it to Ethereal or get somebody else to do so.
