Well at least you're already at 60i. That will help translate to 29.97 real nicely for you. As for making a video for the director to watch, you have a pair of choices there actually.
1) If he/she will be using a laptop to watch it, you could just simply create for them a quicktime movie. Have them show up at your place and you can transfer over the movie file to them. Not sure how universal an HDV codec would be, so you might want to dump the materials into a more universal one (maybe like photo jpeg at 100% quality or even an uncompressed if the director will have enough hard drive space). If you can get away with the quicktime movie option it will be your #1 way to make sure the director has something watchable in time.
2) The actual DVD method...
Select your timeline. File | Export | Using Compressor
Compressor opens up. Select best quality encode for 90 mins (16x9). Select the AIFF option. Then go back and do a second selection and select the MPEG-2 option (both times under the best quality encode for 90 mins 16x9). Set your destination folder for both things. Press the submit button and pray that there is enough time to encode it between now and when your deadline is.
Then open up DVD Studio Pro, use one of the provided templates, and quickly bang together the DVD for the director.
