Using <!-- --> is a bad idea since the WebSRT syntax already uses -->.

I don't see why we can't just consume the legacy and support it in WebSRT. Part of the point with WebSRT is to support the legacy. If we don't want to support the legacy, then the format can be made a lot cleaner. >> Breaking SRT compat means that we can >> go back to requiring UTF-8 as the encoding.

Consider editing a WebSRT file in Notepad, and then suddenly it doesn't work anymore. Instead we should allow the BOM. (WebSRT already allows the BOM.) -- Simon Pieters Opera Software
