     Remove lowres video decoding

     This feature is complex, of questionable utility, and slows down
     normal decoding.

 low-res video decoding is used in mythtv in order to flag a video for
 commercial.

 Removing this mode breaks mythtv's comm flagging.
 Doing comm flagging without low res reduced speed by a factor of two.

 So I would like to plead to reverse that change.
 There was no need to remove it.

 Thank you
