You need to import VIDEO_TS.IFO, then click Advanced > File Information and select the episode in Video > Track field. To preview it, follow to the Edit window.
If you would like to add other episodes into the program for conversion, click the "+" button and add the same VIDEO_TS.IFO once again. Then choose the second title in the Advanced window.
You can split the episodes into separate output videos using the Split feature.
