Using VE to take 720x480i to HD interlaced.. few questoins.

Hello i am trialing this software and once i have the methods worked out for best result will purchus. basically i am after software ( standalone ) that can take my 720x480i DV footage and make it the biggest possible whilst keeping the best resolution. From researching This software i read :

"Super Resolution to double the picture size and then resizing the result to desired size using an image scaling method, That means if you try to increase resolution 4 times, then single pass will apply SR to increase it 2 times and then a simpler in-frame method to increase it 2 times more."

So really the best bet would be to simply double the resoltuion using the 'super resolution' any increase beyond that will not be made just via super resolution mehtod but also by an infirior in-frame method. Is this right ?? so for the best result use VE to take the 720x480i to double its resolution (1440x960i). My next question is that i want to keep the footage interlaced, again reading from the site :

"You can keep interlacing by using filter ViewFields before SR and UnViewFields after SR. These filters decompose interlaced frame into two separate pictures (fields) one under another and then combine them back. So each field will be upsized independently."

Which one do i need to apply ? just one or both ?? And do i simply just add the filter or both ( ir required ). I simply want to keep the footage interlaced, i'm just going from SD interlaced to HD interlaced.

Hope for a reply.

Regards Marty.
