It is 'Pashto' in the area of southeast Afg and Quetta, and 'Packto' in the NE Afg and Peshawar, or 'Peyck-hawar' ( Pex̌awar پېښور ).
The videos from youtube can be downloaded for supplemental audio tracks to your studies. The addon YouTube Downloader by flaviobayer for Opera web browser makes this convenient. IMO however, Pashto is too confusing to try to learn this way.
Instead goto softsonline.org and download:
Pashto Headstart, which contains around 700 commonly used phrases. You only need the mp3 files which are about 250 mbs unfortunately you have to download the entire program (900 mb) iot get the files.
Pashto DLI - Basic Course Semester 1 & 2, this course divides their audio into northern and southern dialects
Dunwoody Press makes the only Pashto-English electronic dictionary that I know of. Its expensive at $75 but it is outstanding.
Avoid both the 1970s textbook by Tegey and the Pimsleurs audio program, the first is inefficient and the other is a rip off.
If you're having trouble downloading from the SOFTs because you're OCONUS shoot me an email from your AKO to confirm that you're military, then I'll send you the materials if you cover shipping and the cost of USB stick or SD Card.
If you aren't able to register with SOFTs, then you can goto
http://gloss.dliflc.edu/Default.aspx and start with the level 1 files. You might still need a textbook, I have never use this one but it appears to be the only one that isn't merely a reprint of a 19th century text.
