Video Conversion Issues with Win 7 Install

videosAs you’ve read in my previous postings, I use a utility called DVRMSToolBox (DTB) to convert my recorded TV shows from DVR-MS format to WMV format for my Zune HD. My previous Vista 32-bit system worked great using this conversion process, but since upgrading to the Windows 7 64-bit OS I’ve had a slight problem with my video files.

First, Windows 7 Media Center now creates WTV files instead of DVR-MS, so I need to add in an extra step in my conversion process to convert the WTV files back to the DVR-MS format for my utility to process them into WMV format. That seems to work ok, using the converter called “dtvconverter.exe” provided with Windows 7.

The issue, is that the created WMV file has a slight audio delay when I play it back on my Zune HD. The audio is out-of-sync with the played video by about 2 seconds, which is really annoying. Now, the same video file plays ok on my Windows 7 desktop PC, but it has the 2-second audio delay when I play it on my Zune HD.

So, I’m not sure what the problem is, as it could be a number of things. To rule out the converter program, I tried using several different methods at my immediate disposal (e.g., Windows Media Encoder 9 x64-bit, Microsoft Live Movie Maker (that came with Win 7), DVRMStoWMVHD (supplied by the makers of DTB), and also the ConvertToFile action included in the DTB utility). None of them created a WMV file that didn’t have the 2-second audio sync problem.

I’m now thinking the problem might be with the Audio or Video Codec that is installed on my Win 7 system. Since installing codec packs can be troublesome, I was trying to use whatever was installed on my Win 7 by default. But, that may be the issue. So, I’ve installed AntiPack, which is a set of codec filters by the maker of DTB which I hope will fix the problem. I’m currently running some conversion test cases now, so I’ll report back if I’m successful.
