I enjoyed the link on using a film camera for meteors, especially the line about the developer saying the film didn't have anything on it.
I've heard that many times. Once I was having larger reprints of a film I already KNEW had stars and a galaxy yet the developer said she wasted lots of paper printing my, "empty roll of film."
Back to using a DSLR for meteors. Not easy, but do-able, I may try myself if the weather is clear. I'd suggest an advance test to find how long you can keep the shutter open without overwhelming noise, in my light polluted location that is about 2-4 minutes. Take several test shots in a row, the noise will increase with time. though if you are in a cool climate like me that will help.
On the designated night aim the camera with wide lens either:
a. Toward the shoulders of Leo (Constellation is named after me). This will show meteors going outward in all directions if you are lucky.
b. Toward the West of Leo since he will be just rising in the East after midnight.
c. Toward the darkest direction if Leo is near a light source but don't go more than 90 degrees away.
You will need to take a lot of exposures of the time determined above if you want to catch a few meteors bright enough for the camera to catch. Remember, the meteor lasts a couple of seconds out of a several minute exposure thus most will be dim. A timer or computer program can be used to sequence the camera. Or, you can put the camera in continuous mode and lock the remote on. The camera will go as fast as it can, allowing for time to do NR if used and store the shot.
You must decide if you want to use NR which will greatly reduce noise at the cost of only having 50% duty cycle. If a bright one goes by while the NR is taking a dark frame you are out of luck. You could take your own darks later on if you know how to process them.
Focusing: It is hard to focus a wide angle lens on stars, they are too small to see through the viewfinder. Try and find a bright enough object to focus on manually (Capella, Mars, Jupiter if still up). Fortunately short focal lengths are not as sensitive to focusing at infinity.
Confession: I've had little luck imaging meteors.
