Maybe you won't be able to find them, you can look for Conan subbed episodes in #DCTP at irc.rizon.net. Many episodes haven't been subbed yet (but you don't need to watch them to follow the original plot of the series).

There you have a list with the important Conan episodes (that list doesn't includes the episodes were Sherry appears and other important parts that were subbed by AConan).
(In #DCTP, just type !DDL and you'll get a link, an user and a password for every Conan episode in DD)
If you need anything else (or I wasn't clear, english isn't my main language) feel free to ask me. :)
