As codecs evolve, the "143 mkv" benchmark may shift. , the new royalty-free codec, can deliver the same visual quality as HEVC at 20-30% smaller file sizes. In the near future, a 100 MB MKV might look as good as today's 143 MB file.

No, not directly. DVDs require the VOB format and specific MPEG-2 encoding. However, you can burn the 143 MB MKV file as data onto a CD-R or DVD-R to store or transfer it.

Here are the most probable reasons for the number "143" appearing in a filename:

Sometimes, file names include numbers to indicate file size in megabytes (MB). However, a 143 MB file would be extremely small for a high-definition movie. It would imply a low-resolution "CAM" recording (filmed in a theater) or a compressed file for a mobile device. Conversely, if referring to gigabytes, "143" is far too large for a standard movie, making this less likely unless it refers to a bitrate value.
