I have tried a lot of different settings and had kind of settled with the thought that it might be the gpio handling that CurlyMo talked about. I also saw that the blacklisting was gone, however I do get the leds to show the colours according to the frame but with the flickering.

I am just using the WS2801 connected directly to the GPIO pins (Data, Clock an GND) and to a separated USB power supply (5V, 2A). Nothing special and no frame grabber.

My rpi 2 is getting its supply from a 5V, 1A PSU. I have just tested it again and I notice no strange behavior during playback from my attached USB hard disk.

Do you also have the flickering when using the android app and controlling your lights?

That is the same setup that I have, also the ws2801 directly connected to the GPIO, with a separate PSU 5V 3A where ground is connected to the ground on the PI2. The only difference for me is that I have 64 leds where you had 49, I even tried your exact config where the last leds would be black but I stil got the flickering.
The Pi is driven from another supply with 5V 2A. And I get the flickering when the leds are changing colour or are updated. I.e. when I use the android app to set a specific colour there is no flickering, but if I use an effect there will be. The more the screen is changing the more flickering I get.

The hardware solution is exactly the same as I had on my previous RPi B and there I had no issue with this. And since setting a colour works it would seem that the hardware is solid.
Strange that it works for you since CurlyMo and popcornmix found some issue with the GPIO handling =/. Have you installed some other hardware or program that might affect this?
