Is it a PAL miniDV camera? If so, your PC should not have any problem to play back the footage. PAL DV files should be Lower Field First, so check the file properties (I think it is called Interpret Footage in Premiere) and make sure this is correct. Also set your project to PAL DV so there is no field order swap going on. This should play back smoothly on your PC, but you will probably see interlace artifacts (horizontal lines and jagged edges when things are moving) because the PC monitor is progressive scan and the footage is interlaced. This is normal and will not look like this when you burn a DVD and watch it on a television.
If the files are not DV format, pelase provide some more info about them.
