Since the first incarnation of the Apple TV back in 2007, the product has received a lot of interest from developers looking to milk it for extra functionality. One such developer, FireCore, is updating its aTV Flash (black) software for jailbroken Apple TVs to version 1.5. The update adds a number of extra features like support for efficient NFS (Network File System) streaming and the ability to manually set a subtitle offset if the timing's off.

aTV Flash (black) allows your Apple TVs to stream file types that don't jibe with iTunes like MKV and AVI, and provides a native-looking interface to browse your non-iTunes video files. FireCore is claiming the 1.5 update improves performance for almost every file type the software can handle, and adds "a mountain of other improvements and fixes," so if you've been on the fence about buying, this would be a good time to try it out.
