Your problem is with XVMC, XVMC is buggy on Athlon64 if you are using the 64 bit version of the driver. The bug has been reported to NVidia numerous times, and we hope for a fix with the next release.
If you must use XVMC (no choice from a quality perspective), you will have to install the 32 bit Nvidia driver and a 32 bit version of linux. David PS. I have the same problem, to solve I use JUST XV, with acceptable results. No Svideo just DVI. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sérgio Gaspar Sent: Monday, August 22, 2005 8:00 AM To: [email protected] Subject: [mythtv-users] Unable to initialize video - was working before Hi, I am assembling a mythtv system on my spare time (which is not much) made of an Athlon64 on a nForce3 chipset, two PVR-500MCE cards, one PVR-350 and an AGP 8x Geforce 6200 card with S-Video out. I am using the S-Video out on the nVidia card for connecting to the TV and image quality on the TV is reasonably good when using XvMC, but not so good without XvMC. I insist on using the Geforce for video out, as I will try to connect it to the SCART on the back of the TV set using RGB for better quality. Now, my problem is that after about two months without spare time I tried to use the system, but when I try to watch TV I get the "Unable to initialize video" error, but it was working two months ago, why not now? No configuration had been changed since, as the system had not been used. While experimenting a little to solve this issue I was able to watch TV twice but strangelly it only happened after using the nvidia-settings application for increasing the overscan value and then decreasing it, but not on the same X session. The first time I run mythfrontend after doing this got XvMC working twice, nothing I could do would get it again, including desperate solutions like powering the system off and then back on. Since then I tried different versions of the nvidia kernel module, with no results. mythtv is version 0.18.1, nvidia kernel module versions 1.0.6629, 1.0.7676 and 1.0.7174 have been tried along with corresponding nvidia-glx versions. The Linux distribution I am using is Gentoo. Without XvMC I get lower resolution choppy video (unpleasant to watch), and after a while (30 seconds is enough) the system does not respond to the remote control or to the keyboard. I believe an Athlon 64 3000+ (Venice core) should be enough for decoding a few streams of MPEG2 video, in fact, mplayer plays a DVD in full screen with much more quality and much less choppyness, and unfortunatelly I can only stop it with Ctrl+Alt+Backspace when run from mythfrontend. Another strange thing I noticed was that the overscan on the TV set was insuficient, same setting as two months ago, but I suspect that has probably to do with variance with temperature on the analog circuitry of the TV set. Any ideas on the "Unable to watch video" issue? Thanks in advance, and sorry for the very long description.
