This question seems to come up with every new Infinifilm release. The answer is that none of their Infinifilm titles they have released have come with English subtitles because the Infinifilm track takes up the space that would be occupied by the subtitles.
This refers to the R1 Infinifilm releases.
Well these "inferior" films do not contain any subtitles in any languages and no other sound tracks either. I cannot believe New Line would sink this low and remove some of the most important features on DVD.
I wish they will realize this huge mistake and start supporting subtitles again.
An Infinifilm special features do not take up the subtitles track (which I believe can contain upto 8 tracks - or maybe 32, it could be 8 for audio).
Regardless, the Infinifilm subtitle track does not appear all the time, nor does it appear if you are not watching the film - the 'infinifilm experience'.
Finally, the English subtitle track could be placed anyway on the screen at the time the Inifinifilm track is being displayed.
This is just a cut-corner approach by New-Line which really annoys me.
Just like the problems with Terminator:SE and Mummy Returns lack of on-the-fly switching. Why have those features when you have to stop the film, change the option, and then resume the film. What a waste.
