My questions is whether the high-end Blu-ray players that cost several hundred bucks more than the one I got do a better job of this.
You’re probably experiencing what is called “Interlacing” which can cause the jagged edges in video..It also happens with sub-titles at times as well..which is why 120 HZ motion correction was created, to help correct this phenomena with sub-titles, in addition to helping to correct motion blurring.
If you have an older High Def tv set; without 120 HZ, then you’ll possibly see artifacting of this nature when watching sub-titles.
Perhaps your dvd player has a switch (found in the settings) that will allow you to change the output display from Interlace to “PROGRESSIVE”. I think many of the newer dvd players do this automatically..but some of the older dvd players have that switch.
I hope this suggestion will help correct this problem.
