Just a further update on my issue. I successfully converted a .wtv file to.mpg (mpeg 2) using graphstudio and the ATI mpg file writer, and then tried to convert that file to dvr-ms using todvrms and again no go. The command line box never closes and the resulting .dvr-ms file is short a few hundered KB and when I try to play it, the video looks fine, but truncated and the sound is out of synch by several minutes. The file tends to play for a few seconds and then stops also. Again, I'm running VISTA x64 with the TV pack. Would that make any difference on trying to convert files from mpg to dvr-ms??
Also, did anyone EVER successfully edit out commercials of a recording (dvr-ms OR wtv) on a VISTA x64 TV pack box?? Not just skip the commercials, which appears to work sporadically for me btw(in VISTA MC I can't find the DTB pluggin listed anywhere, even though I get prompted if I want to scan a file for commercials sometimes), but cut them out.
It seems like most video editing software I try doesn't work properly under VISTA x64(like videoredo for example) also. Is this a sign, I should just make the jump to Windows 7 x64, or is that going to be any easier? I guess, this is getting off topic from my original post though!
