unable to convert full video from mkv to mp4

[srikanth3d]

When i am playing mkv video in TV, only audio is played, no video at all.
So, i tried converting this mkv video to mp4 format with MKVtoMP4 software [http://convertmkvtomp4.info/]

But the problem i encountered while converting is that only 32 seconds of video is converted into MP4 and software says conversion completed. Actual video duration is more than 2.5 hrs.

Please guide me to solve this problem,
thank you

My favorite MKV to MP4 is YAMB.
Others are praising Video to Video Converter
In the latter, load your file and select 'Direct Stream Copy'. Just change the container to MP4.
One of those might work better for you.
