Sorry if this comes across as stupid....I see the example 4:3 PAL and 16:9 PAL in the 1st post. I'm in the USA so the broadcasts are NTSC (ATSC now that it's all digital for OTA?). Would I have to make changes based on that? I would like for the 4:3 broadcasts to auto zoom in on my wide screen tv.
Thanks for your time in advance.
It doesn't matter, it's just a name for a rule. You can name them 4:3 NTSC and 16:9 NTSC if you like.
It's al about pixels and ratio. And check the mediaportal.log file to see how the rules are working out.
