These resolutions are fine for projecting at 800x600 on a 8x6ft screen. No one is closer than 20 ft from the screen and the only people noticing the pixel problems are the Media techs at that point.
It could be better, but it works, and it makes the process so much easier. Yes there is the inability to repeat a chorus 3X, but if you've seen these videos, you'd know that they already repeat the chorus enough times already.
I've seen other forums where serious techies scare off newbies from products because of insignificant technicalities (I can't pick a DVD burner for that very reason). So don't scare off the smaller churches from using this by degrading the product too much. It is not meant to be "Crystal Cathedral" quality, but these videos in this format make it so a small church on a budget can look really professional with one guy running the show. He just has to hit "Go live" to get the party started instead of performing 3 or 4 tasks to get things started from a DVD.
