OK, i just found a way to handle the problem.
The original filenames are file.MOV // when I change it do file.mov without upper cases it works, but is there an easier way?
have you checked your import settings are set to HDV and not DV on the capture window?
What version of Premiere?
hm I dont use the Capture Window, just DragnDrop. Worked for me for years, also with the DSLR Files but from now on...
