How to make better DVD's and eliminate aliasing

Question

After trying several different ways on how to get the best from my AVCHD camera to an SD DVD I discovered the following worked best.
1. Import and edit as per normal
2. Export to HD 720p (DON"T share to Dvd Studio Pro or iDVD)
3. Open iDVD and import the HD 720p file directly from the saved folder (iDVD will convert it to mpeg 2)
4. If using DVD Studio Pro you will need to convert the HD 720p file to Mpeg 2 using Compressor as normal.
5. Burn dvd.
This way eliminates nearly all of the aliasing problems and overall quality looks much better than just "Sharing" directly to iDVD or DVD Studio Pro.
Give it a try and let me know if your dvd quality improves.
Hope this helps.
Cheers

First of all; your way of attacking this is creating a very specific subVI. It is a general rule that subVIs should be as reusable as possible, so they should just perform a task upon some standardized input. That's why i suggested that you use an array input (but forgot to mention why...).
I've attached a small example of how i would handle this sort of problem. See the attached VIs, the subVI only handles the task of setting visibility on or off. The array input is dynamic in size, as opposed to the cluster, so any size 1D array of control refnums can be passed to it, using the boolean input to determine visiblity setting.
Your other question; yes it is possible to reach the control references from inside a subVI by passing the "This VI" reference to the subVI. But again, you'll have to change the subVI or make a different one for each different set of visible/invisible controls for it to work. Which is why i recommended building an array of just the refnums of the controls you want to set visibility for, and pass it to the subVI.
