In the updated CD/DVD version, True Shot and the damage portion of Crossbow Expertise do not work.
The 1.34 patch is just required for older CD releases. The DVD release (1 disk) has already been updated, as will be any of the newer CD re-releases (3 disks).
Check the version number shown in the bottom right corner of the main menu in the game; the latest is 1.0034A, so you would only need to install the patch if the version is lower than that (ie the original English release was 1.0029A).
