Alright - lets roll out some facts.
Your 7 - You have plans to create a HD PMX? Neat! Do tell me though, there are a few compression ratios to consider, especially when it comes to using something like an INCA based PMX unit, what compression factor would you plan on using, keeping in mind you have to keep the headend happy with a suitable bit rate! Understand any of that... or did Arthur come back on PBS and you got distracted?
2nd of all, TWN has NO plans of going HD as of yet. Trust me, there are enough issues with the SD networks that they havent even touched on the idea of a HDcast yet. You know the PMX's can barley handle 480i, let alone 1080i. For the past 3 years, there has been NO budget for anything PMX related. The latest QSU from Pelmorex doesnt look to promising for the future either.
"Yes I will also I will am buying a PMX unit today and use the files".. Uh huh.. PMX's are not available to the public, you cannot buy them off the shelf. You wouldnt be able to use the files anyways since they are HARDCODED in to the application.
