It should be possible to import TS MPEG-TV videos to Pinnacle Studio and use them to a new or existing project, which is what ts to stx conversion essentially represents. However, this is not a file conversion in proper meaning, as projects are generally not regarded as videos up until they are exported to actual video format.
This conversion entry was verified by us and conversion was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it is not possible because incompatibility between programs, caused by closed file formats, very limited support etc.
If you find entry that you feel is flagged as bad wrongly, please tell us in the discussion below with as much as information as possible so we can fix it.
