Re: Correction Re: [DDN] comparison of video blogging compression techniques
Yeah, I noticed that soon after sending it out. I corrected it on my blog but hadn't gotten around to sending a note to the list, so thanks for being on top of it. ac Dave Pentecost wrote: Hi Andy Others may have caught this.
