Rick: I have to ask the obvious question: Are those episodes in the database?
If they are in the database, then my guess is that you might have had difficulty getting them entered because you started from your own page and tried to submit the episode titles. The formatting of episode titles on IMDb is complex, and if you get any of the punctuation or spacing wrong, the database won't recognize the episode. The way to get around this is to start from the episode page, and submit your name to the page, rather than the other way around. This way, you only have to get your own name correct, rather than trying to get the episode title format correct.
If the episodes are not in the database, you can submit them, and submit your name to the cast of the episode in the same process. Go to the page for the TV series and click "Add episode", then follow the instructions.
