I normaly just capture the m2t then convert later but I wanted to try to capture and convert at the same time using that selection in Connect HD. but as I did it captures fine then occasionaly I get an error of "buffer underun while capturing data to disk.try defragmenting youre drive." all my drives including the C drive and the empty drive im capturing to(internal SATA) were just defraged 2 days ago.

But what Im wondering is does this apply to the clip just prior to the error or after.
and do I need to recapture the m2t file that had the error or just reconvert that m2t to an intermeadiate.
Anybody had experience with this error here.
I have submitted this to the cineform site too, but I know Thad is a busy guy, and also monitors this forum as well.
