The information isn't obsolete, but evergreen (not changing). At most, it needs some additions, discussion of more modern OS and workarounds required. Certain guides dealing with restorations and workflows have a few more options.
The DV info is all still accurate, both myths guide (thankfully, those are now mostly gone), and transfer method guides and software.
The last version of
VirtualDub official is 1.10.x, and it had capture issues.
VirtualDub FilterMod (FM) is a fork, renamed VirtualDub2 later. Same 1.10 issues.
VirtualDub2 changed things, usually for the worst, it often causes dropped frames internally to itself. Yikes! Only some cards were "improved", meaning Win10 capturing is still possible with 2 while 1.9/10 was nuked.
If specific questions, ask.
Not just "is all this stuff obsolete". No, it's not. But I'll review anything that needs clarification. I do still make text updates to the guides, when time available. On next site update, I want to redo all the images, massive undertaking.
