Not an expert, but VLC can also do batch conversion, command line etc.

what media converter u guys recommend?

I use Movavi Video Converter, which can convert almost any format to almost any other format. It also has some editing capability, such as cropping, trimming, audio levels, etc. It's 55 USD for a permanent license on one machine.

It has some nifty features, such as allowing you to select which audio and video codecs the final product has (especially good if your "smart" TV only recognises some codecs), and variable conversion quality so that you can choose the size of the output file (in case it's a bigger file, and you want it to be <4GB so it fits on a FAT32 thumb drive).

What is a TS file?
A TS file (Transport Stream) is a TS videos stream file used to store video on a regular DVD with the .ts file extension.
Thus, the .ts file is used primarily to save broadcast or streamed video.
