Error with m2ts files I haven't seen before

I'm trying to load footage files transferred from my AVCHD camera onto VirtualDub to run Deshaker on them.

This used to be as simple as doing a script like:

DirectShowSource("00037.mts", fps=29.97, audio=false)
AssumeTFF()

But now, if I try that script, or if I try to open the file in MeGUI's AVS script creator, it gives me this error:

I tried creating graphedit files changing to the ffdshow video renderer, both normal and DXVA, and I get some other type of error, but still an error.

The same happens with any mts or m2ts file I try, but I can play those files without problem in Windows Media Player or any other player.

The same script above used to let me load the files in Virtual Dub just fine not long ago.

Any ideas?

DirectShowSource("Way before file\00037.mts", fps=29.97, audio=false)

DirectShowSource("Way before file\00037.mts", fps=29.97, audio=false)

If you're talking about the path, it's not necessary as long as the file is in the same folder as the avs file. I always do it that way to avoid having to type the whole path. Plus, this error comes as well when I try to load the file in MeGUI's AVS script creator, and it didn't use to happen.
