Yeah, we did not have the lockups while using a monitor, and everything seemed to center around the use of the ivtv frame buffer and X. Your situation may be different since your using normal monitor out, but hard to say. For us, it only took a couple pings to bring the box back to enough life to exit tv, or whatever.

I agree, DMA/IRQ something is broken, but the trend seems to point to hardware and not software. The PVR-350 proably uses alot of bus traffic, so faulty hardware may not show up running normal stuff. Maybe there's a software workaround, not sure. Disabling other DMA devices sure tends to help, if it doesn't slow you box to a crawl when commercial flagging, etc. -Kenneth On Fri, 11 Mar 2005 22:15:05 +0100, jerome lacoste <[EMAIL PROTECTED]> wrote: > On Fri, 11 Mar 2005 15:50:02 -0500, Maverick <[EMAIL PROTECTED]> wrote: > > OK, since there seems to be a ton of people on the list lately > > complaining about the lockup issues with PVR-350's, using TVout, I > > the thing is that the lock ups happen even if we don't use TV Out. > > I don't I am on a monitor. > > > the system would just freeze.
