Generally true. But some standalone DVD recorders record with the wrong field order/dominance, which may cause flickering problems when the recorded discs are played back on some equipment. NTSC DVD is generally BFF (Bottom Field First), but my Panasonic DVD recorder always records TFF (Top Field First). My newer DVD players have no problems with these recorded discs, but my earliest, 5-year-old DVD player (which was supposedly compatible with burned single- and double-layer media) could not play such discs back properly (with lots of flickering and jittering).
In addition, all NTSC analog video formats are always BFF. This can result in flickering and jittering problems in the finished DVD.
On the other hand, if your analog video equipment is a PAL unit, then you should not have any problems unless you by chance acquire a supposedly PAL-compatible DVD recorder which somehow records BFF (since PAL has always been TFF).
