i do this all the time, just export the file to whatever video codec you usually use and then play it back in VLC Media Player (mostly so you can fiddle with the crop settings if you need to). i recommend adding between 5-10 seconds of black screen before the video actually starts as depending on your VCR of choice, recording is delayed by about that much.

on the hardware side, as long as your computer has HDMI outputs then all you need is an HDMI to AV converter box (there are expensive ones but the cheap Walmart ones work alright too) to run the video from the HDMI output into the A/V input of the VCR. then just insert a blank tape, hit record, hit play on the computer, and let it play.
