Burn Standard Definition to Blu-Ray? -4 archive

[MarkQC]

I've been burning my eyes out for a few weeks now trying to find the answer to this question (clearly, unable to find it in search here or anywhere else).

For a year now I have a sony Sony HDR-XR500V 120GB High Definition Handycam which came with Sony PMB (Picture Motion Browser) Software which is enabled and works fine with my blu-ray burner. I also have Sony DVD Architect Studio 4.5 - but this does not burn blu-ray apparently.

I have oh, probably 300 hours of standard definition video starting back from the late '80's. So sure, some beta, VHS, HI8, miniDV.

Now I DON'T want to burn all this onto regular DVD's as this would be a bunch of them, and I want a better disc for important family archive material like this anyway - even if it is only at regular resolution.

I have already started capturing it all to a hard drive. I used windows movie maker and captured it at 720x480. Now I incorrectly assumed that I could import/convert this into the Sony Picture Motion Browser software to burn to Blu-Ray but noooooo, and as mentioned the Architect 4.5 doesn't do blu either...

So how to take any saved media files (WMV/whatever) convert them to something that can be imported (still as a standard definition, even 4x3) into some kind of blu-ray authoring software so one can save 12 hours or so of standard definition video on a single blu-ray disk?


ANY ideas that are simple for a bone head like me would be deeeeeply appreciated
