Now the hdtv clip is quite choppy. It works OK for the first 1-3 seconds, then gets all choppy. At least I have a picture :-) The sound gets choppy, too, BTW. just read this thread for the first time.. could be *completely* off kilter here.. but if your running seperate frontends and backends.. could it be a network problem? cables/cards/hubs/switches etc?

Re: [mythtv-users] XF4.3.0 too slow for HDTV? (was BadAlloc)
I feel for ya. Nvidia drivers have given me nothing but problems as well. It turned out in my case to be hardware related; the video card and the mobo chipset didn't get along (though would work if reduced to 2x agp.) Suprisingly, though, even though it crashed on the desktop all the time, it still performed better, and without crashing, than my radeon 9k in glx games. -Nate On Sun, 5 Dec 2004 12:36:09 -0800, Brad Templeton <[EMAIL PROTECTED]> wrote: > > I am also having a nightmare with this.

Re: [mythtv-users] XF4.3.0 too slow for HDTV? (was BadAlloc)
I am also having a nightmare with this. My efforts with a Radeon board were unproductive on an Athlon 3000. Choppy video, reversed colour, a bright purple bar on the right side of the screen. Radeon 9200se. NVidia has been a nightmare as well though. The drivers are flaky. The latest 6629 driver crashes the latest Xorg and 2.6.9 kernel. xmvc worked on a 2.4 kernel but has not yet worked on 2.6.9 for me. Sometimes I get the blue xvideo of doom, where all xvideo screens are just a blank bright blue. Sometimes you can get rid of it by removing the nvidia driver from the kernel, and re-inserting. Sometimes a hard boot is needed. Yikes! When it is working, with xvideo, I show about 10 to 20% idle playing HDTV, which is not enough of a cushion, but it works if the system is quiet. With xvmc (in mplayer) it's much better, about 60% idle. However, I have not managed to get xvmc to work with myth. The rpms don't have it compiled in and my efforts to compile myth have failed due to some bizarre library problem I am having (probably due to the fact I upgraded RH9 to FC3) However, the reports from people I have read about xvmc in Myth suggest it is not ready yet, so I have not tried too hard. Better has been a Pentium 4-3ghz. Reports are that P4s blow away Athlons at mpeg tasks. The benchmarks are quite clear on encoding, I have not seen benchmarks on decoding, but my own tests show about 40% idle time, if I recall correctly, on the P4-3ghz than on the Athlon-3000. Why? Well, as you may or may not know, the Athlon-3000 runs at just 2.2ghz. AMD's processors normally are faster on typical applications, so AMD started putting the number on them to say "As fast as a Pentium at 3ghz". And largely they are right -- in fact at many tasks they are faster than the Intel at 3ghz. Athlon-64s are even faster, and so the A64-3000 is just a 2ghz chip! However, when you have particular algorithms that have a series of steps with predictable branches, like mpeg, raw ghz is what makes the difference. So if buying a processor just for myth, consider Intel again. The downside of Intel is that because it is really running at that clock, it runs hotter. So AMD is a better buy for most applications, but not mpeg. So only the nvidia is fast enough even in xvideo mode but alas, I can't get it to drive my HDTV at 1080i or 540p. I get a "double vision" problem that looks like an interlace offset error. I don't get it from the Radeon, nor from the NVidia under powerstrip. But I remain hosed so I may be forced to take the nasty step of returning my HDTV. ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
