(I'm in the UK)
I've recently accepted to help a friend out by editing something for him.
I work all day everyday in the same formats and settings ( which is pretty shitty cause things like this really catch you out). Although I had told him to always use 25fps unfortunately he's gone and shot in 23.98.
I realised whilst trying to export out a timelapse as I was consistently getting a General Error.
Now to be honest I have no real idea what problems this can cause me. I've reset my sequence settings to match the footage but would really like to get a heads up on any potential problems it could cause me.
We do that with a lot of 23.98 material. It works fine for both DVD and BluRay.
I suspect there's a bit of difference however getting to 25 fps as almost all of what we do is NTSC and 23.98 is an NTSC variant, hopefully you'll post a follow up as far as what level of success you've encountered
