Recent advances in digital video have lead to a convergence of mainstream entertainment (e.g., movies) and language learning tools. An example is a software system/media player called L1, which provides interactive subtitling and learning support for DVD entertainment products. Convergence of entertainment and learning resources raises challenging language learning software design tensions. The article reports a study of English language learners who were asked to use the L1 system and to rate the system features in terms of ease of use and learning. The results showed several distinct design preferences depending on the user's more general attitudes toward edutainment resources. The article discusses L1's consequent design modifications. as well as design considerations for language learning edutainment resources more generally. (Contains 2 figures.)
