These Murli are not complete verbatim as per BKWSU, but many, including all the recent ones, are substantially as per BKWSU, with tidied up in syntax and language. Some comments to individuals are omitted in some.
Many of the older ones are summaries, more or less as published elsewhere on this site, which may lack certain passages, and certainly will have repetitions removed.
There are currently almost 500 Avyakt Murlis here, with a few trance messages also, from 1969 onwards.
Missing Murlis are being added, and omissions in summaries are being reinstated, as and when availablity of source copies, and time, allows. For example 1969 Murlis are now substantially complete. Sakar Murlis may be added later.
Anyone who considers the Murli to be the immaculate words of God may have problems with the (very minor) liberties taken in the conversion of the original materials, but the aim is to make the material clear and accessible.
For those that need original copies, http://jewels.brahmakumaris.org/ is providing full BKWSU originals (in PDF) from the last 2 seasons, with no registration required.
I have no knowledge of the completeness or otherwise of the youtube materials.
