The latest TXD revision is TXD2009. As with each revision, there are some major changes. Multiple CD releases aren't necessary anymore, but most release groups keep following the tradition. The maximum width of a rip is lowered back to 640px for WS releases, the movie length versus file size rules and many other sections of the ruleset are redefined or extended. 91 releasegroups have signed the rules. as with the 2005 standards, there is a rebuttal that aims to allow ""SOME of the fuckups and insanity in the 2009 ruleset"". While the 2005 rebuttal made some valid points, this one is regarded as being pointless by other sceners. The reason for lowering the resolution is that some cheap Xvid players don't fully support resolutions above 640px. The pixel aspect ratio goes bad and makes the movie unwatchable. Other points made in the rebuttal are too hard to enforce, while still being backed by the releasing groups, or that the TXD is mainly meant for retail sources. Not all rules can be enforced on non-retail sources.
