Anyone had much success with this? I have mkv videos that I had backed up but was wanting to play them over the TV rather then sitting at the computer all the time and ConvertXtoDVD seemed to be the answer but 1 in 4 usually fail. For those looking to play mkv on a standard dvd player suggest you use the software at your own risk. My first attempt at this the conversion process came out to something larger then dvd5. Even though I had it set to this it would still somewhat overlap more by 100-300 megs. I removed all my codecs and started over using what was needed to play general video formats and mkv as well. Once I got all this updated I was able to convert mkv containers some what faster and the over all video_ts file size always stays well below 3 gigs even though the mkv file is 4.3gigs. The problems I run into with the failed ones are mostly audio playback. With VLC I can select the audio format, rather it be 5.1, stero or mono. When I use ConvertX it doesn't give me an option to choose a default audio mode so unless the DVD player allows me to change the format which usually doesn't I have a failed DVD. Second problem I run into is video playback. It has audio or no audio at all and the video runs at 1/4 of the speed but if I play in my computer it runs just fine as if nothing is wrong. Maybe I need new dvd players who knows...I have had some success converting mkv to Xvid format then to ts but its a long process and you definately need some CPU to do it if you want to do other things on your computer while its converting like browsing the net but I wouldn't suggest it.
