I actually had one other problem. Using tsmuxer and imgburn, i was able to make good playable DVDs of all the EwokGroomer's mkvs but EPIII, which results in an image file slightly too large for the DL media I'm using. The overage is VERY slight, however there's nothing to remove from the file and I know he optimized these for DVD-9 media. My question is, in terms of available writing space on the black media, are some brands of blank media better than others? (I'm currently using TDK.) And do you recommend DVD+R DL or DVD-R DL? You guys are all far more experienced with such matters, so any advice would be really appreciated.
