ak, I have a suggestion, just in case you decide to tweak the app a little in the future. I figured it wouldn't be to much work to implement. My suggestion is to add the option of naming the avi files after the srt's. Cause the srt's I download are very often nicely labelled with episode names and everything, and the avi files you get on torrent or often very messy in their naming.
However, I understand if your priorities have shifted to other projects. Just wanted to let you know people still use and enjoy subdude.
