Convert IFO to M2TS

It doesn't seem likely that you can convert or export single .ifo files to M2TS or any other video format, whic his what ifo to m2ts conversion represents. However, you should be able to convert whole DVD media (.ifo, .vob etc.) to a single video format (like the  M2TS), with some dedicated DVD Ripper software specially designed for this job. Although using .m2ts files is probably somewhat uncommon for ripping purposes.

What it does is that it grabs and convert video data and saves them in one of the multimedia files, often compressed. This may lower the quality compared to the original.
