MKV file conversion before using in DMF6

I know that DMF won't accept the MKV format, so I need to convert it before importing it into DMF, but when I tried using that Super! program (which was recommended to me in another thread), the sound was out-of-synch. It probably had something to do with the settings I chose in Super! to keep as much of the high quality as possible....but can someone who knows the Super! program suggest what particular settings I should use when converting an MKV file inorder to keep the aspect ratio and original sound....bitrates and all that? I figured I should keep the original size and allow DMF handle the compression so my final project/disc will have really good quality.....but is it really necessary for me to have a huge filesize or can I convert the MKV to a standard DVD-compliant setting (which is usually 720x480/16x9) and have it look good? Do the bitrates of the converted file have to match the original bitrates to keep the sound in-synch? I figured Super! would be the best program for the conversion, but I've also noticed I can use Any Video Converter and VirtualDubMod to convert also (although VDM only converts to AVI).

As far as I'm aware mkv is container, much like avi, and can contain many file formats.
Try something like Gspot or avicodec to find out what is inside yours. This may help in deciding which app to use.

What are your aspect raito and frame size?

This is what the information was through the analysis thing in the Super! program told me. I'm also selecting only the English language stream, by the way, for the conversion.

ok, it's an avchd file.
If you are writing it to a normal sd dvd, then you may as well downconvert to sd whilst working on it. I can't see why super is giving you an oos audio/video stream, so maybe try another conversion app?

In other words, do a standard 720x480/16x9 MPEG2 conversion, just as I normally would for any other video file (such as AVI, etc.), right?

I'm running the conversion right now in Super!....will the fact that the source file is a higher resolution affect the quality of the downconvert at all? I'd assume that this, going from what I have (as I posted above), would look better than if I had started with something like an AVI file.

The better the priginal file the better the end product, but SD can only be so high in quality. A well recorded original sd file will look better than a poorly recorded hd file.
