It is said that they do not broadcast in HD video in an attempt to increase DVD sales, or because they are planning to release the HD remastered versions again after the widespread adoption of next-generation DVD, and the broadcasting of videos which have been intentionally degraded is a method frequently used by TBS (and its subsidiary, BS-i) (on the other hand, works produced by Mainichi Broadcasting System, Inc. (MBS) and Chubu-Nippon Broadcasting Co., Ltd. (CBC), which are affiliates of TBS, have been broadcast in the HD master versions in recent years).
HDのまま放送しないのはDVDの売り上げ増や、次世代DVDが普及した後にHDリマスター版で再び売り出す事を狙ったものと言われており、故意に画質を落とし放送するのはTBS（および子会社のBS-i）で多用される手法である（その一方で系列局の毎日放送（MBS）や中部日本放送（CBC）制作作品では近年になってHDマスターでの放映を実施している）。
