Sadly the bookmark feature is no longer available on any of the more modern Humax pvrs. The closest you have is the resume from the last played to point. Just one of the really useful options like jump to a direct time code entry entry punched into the remote control and the use of the colour buttons to support other functions now no longer supported.
Yes there are certain features I do miss (directly visible LED , clock info to name a few) but I have to admit, whilst it is early days, I am liking the latest Humax unit.
