Recover *.MTS files

[monchito]

I accidentally erased videos from a hdd sony cam, fortunately recovered almost all *.MTS files, but can´t play or convert half of them. My guess is that the header or files are corrupt.
Any ideas? 8)

tried it, but sends a message: cant read stream type and doesn´t read *mts files by default.
Tried by changing extension to *.m2ts
doesn´t work
