After update Ubuntu 10.04LTS and 1.24.2 picture flicker

Seems to be wrong driver

[ 35.017666] bttv: driver version 0.9.18 loaded
[ 35.017669] bttv: using 8 buffers with 2080k (520 pages) each for capture
[ 35.017969] bttv: Bt8xx card found (0).
[ 35.017987] alloc irq_desc for 18 on node -1
[ 35.017989] alloc kstat_irqs on node -1
[ 35.017998] bttv 0000:00:0a.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18
[ 35.018008] bttv0: Bt878 (rev 17) at 0000:00:0a.0, irq: 18, latency: 32, mmio: 0xf69fe000
[ 35.018029] bttv0: using: *** UNKNOWN/GENERIC *** [card=0,autodetected]

[ 35.018068] bttv0: gpio: en=00000000, out=00000000 in=00f360ff [init]

Worked just fine ZM 1.23

USB camera looks good in Cheese, but also flickering in ZM 1.24
I have tried to move Conexeant to another PCI slot, the problem still persists.

Hudibras,

I just installed ZM 1.24.2 and bttv 0.9.18 for the first time and I'm also noticing flicker. I, too, am using a video card based on the BT878 (in may case, a Provideo PV-143). A couple questions about your previous installation, if the information is still available:

* What version of bttv was running before your OS upgrade? Could the problem be there?

* Have you tried regressing to ZM 1.23 on your new OS? If so, any improvement?

I'm continuing to experiment with ZM and bttv option settings, but so far, I have not noticed any change in the flicker (or much of anything else). I've also looked to see if there's a later version of bttv, but that's the version contained in the latest Linux Media source archive.

I'll post any discoveries and would appreciate hearing of anything you may learn.

I don't recall the driver, but now it says booktree.
I don't think regressing is possible.
I have found a link there a zm1.24 runs the same board under Unbuntu 10.04LTS
I'm doing some research later today, there maybe a solution in the link. i'll send post it here if useable.
