I have surveyed these, but in general, they simply don't come anywhere close in quality to that of courses offered by edX.
An example that readily comes to mind are the courses on manufacturing processes offered by both MITx and NPTEL. The MITx course was clearly a class apart - you actually got to see the processes in question and how they were applied in the real world factories. When speaking about how a product was made, the lecturer actually bothered to bring samples of those products, sometimes dismantled them, and showed us how they could have been put together. I only audited this a few months ago, and to this day I remember the concepts vividly.
On the other hand, in the videos I watched, the NPTEL course lecturer simply read out from powerpoint slides, which he prepared from a standard textbook. You were better off reading the textbook directly than watching the video alternating between the slides and the lecturer's face. It was a very uninspiring, depressing experience.
