help. captured DV tapes but codec says DV (Sony) not DV

[cypher007]

ok so some years ago i captured some DV tapes using my Panny MX500 via firewire to PC, these have a codec ID of DV. ive just done some more using Win 10 and a PCIE firewire card and these say DV (Sony). im guessing when i put klite on to try and get a DV codec on plus all the other mucking about ive installed a Sony DV codec.

ive only done one tape so can easily start again but im not sure how much the codec affects captured files from DV tapes?

also is there a way of removing the Sony codec and using the DV codec that i used before? ive uninstalled klite but its still on the system somewhere.

finally the files i captured before had a file name of the date recorded and a modified date the same. when i used windv it does similar but wants a name in front and uses todays date. im wondering what i used before to transfer them? scene alyzer uses the correct date but still needs a name in front of the date, it cant just create the files with the date as the name.
