Hi David, i am having the same issues on loading JVC 720p-25/50. I tried it on Vegas 7 and it downloaded fine and as such i am capturing on V7 only……….V8 seems to have a huge number of bugs and no support as i have had it for 7 months and am yet to get a full production from the beast. Binning your captured material also caused a total crash………
Cheers
Tim
