I'm still having artifacts when watching hd livetv channels with advanced deinterlace. Even if I watch 720p channels there are artifacts.
Any news on this front?

I did add some settings you could try tweaking so see if they help. Use this firmware:
https://dl.dropboxusercontent.com/u/3669...re_arb.zip

(Use start_x.elf and fixup_x.dat and replace your OpenELEC start.elf/fixup.dat).

This has a new command you can run from ssh. It allows setting the priority of different blocks on the Pi.

Code:

$ vcgencmd arbiter
usage: arbiter [ status | algorithm <arbiter> <credit|priority|hybrid|delayed> | set <block> <priority> ]
$ vcgencmd arbiter status
SYSTEM_UNCACHED: alg:hybrid
      SYSTEM_L2: alg:hybrid
     SYSTEM_SRC: alg:hybrid
    SYSTEM_PERI: alg:credit
     SYSTEM_DMA: alg:credit
   VPU_UNCACHED: alg:hybrid
         VPU_L2: alg:hybrid
            CAM: alg:credit
    HVS: pri:12 panic:15
    V3D: pri: 0 panic: 0
   H264: pri: 8 panic: 0
   JPEG: pri: 0 panic: 0
   TRAN: pri: 2 panic: 3
    ISP: pri: 4 panic: 0
    USB: pri:13 panic: 0
ARM_UC: pri:10 panic: 0
ARM_L2: pri: 5 panic: 0
ARM_PER: pri: 8 panic: 0

I think the first test is to make HVS low priority and see if that helps.

Code:

vcgencmd arbiter set hvs 0 0

You might also want to set the ARM to be high priority

Code:

vcgencmd arbiter set arm_uc 15 15
vcgencmd arbiter set arm_l2 15 15
vcgencmd arbiter set arm_per 15 15

Or low priority

Code:

vcgencmd arbiter set arm_uc 0 0
vcgencmd arbiter set arm_l2 0 0
vcgencmd arbiter set arm_per 0 0

USB can't be changed when running, so you can't change that.
V3D should have an effect, but we have experimented with that before.

this setting works best for me

but still some rare artifacts

hvs 0 0 and or arm 0 0 are even worse

green artifacts are still there when watching 720p channels
could this be a usb problem and no deinterlace problem?
today I tried setting usb to 1.1 with dwc_otg.speed=1 but my tv card doesn't support usb 1.1 so I can't test if it would improve anything.
