I live overseas and was wondering if the Magnavox 515 or 513 will work with a PAL system?
These machines are meant for use in the States (and, I assume, Canada) and record in the American TV format. Their tuners are NTSC/ATSC/QAM, which means they wouldn't be able to tune TV channels broadcasting in the PAL format. (Of course, if your digital format is the same as American, which I doubt, that could be a different story.)
The recorders also wouldn't be able to make use of an electrical source that differs from the N. American norm.
Whether they can PLAY discs in the PAL format, I don't think anyone's ever discussed that.
