| Post subject: | After R4V3 upgrade, live TV still freezes, |
Well, when running R4V2, I would hit this problem and I would just chalk it up to the apic issue. So I just upgraded. Now, the first time I select 'Watch TV', everything goes great. The second time, it freezes after a few seconds, and In the mythbackend log I get: Couldn't read data from the capture card in 15 seconds. Game over, man. I am running myth on a shuttle SV25 ( North bridge:VIA Twister-T PN133T South bridge:VIA 686B), with a 733Mhz PIII, 128Mb RAM, PVR250 (the OEM model w/o remote) WD 160 Hard drive, home-made lirc receiver, and lite-on DVD-ROM.

Dude the apic issue is with nforce motherboards. The problem with via motherboards is a dma bug and there is no known solution, other than getting a different motherboard. |

Considering that this seems to crop up quite often, and so far I have not heard of a solution from VIA, I just checked google for anything similar, perhaps 'via dma throughput', and see that Toms hardware spotted a issue a couple of years back where the VIA chipset was recognizing that the drive had the capability, but wasn't passing the data at the expected throughput. One of their testing solutions was to drop a Promis UltraDMA66 board in the motherboard. Testing after that showed a significant improvement through that board, over the motherboard connector. I am going to see if doing that provides a workaround for this issue. If not I will be doing a motherboard and version upgrade, as I am getting kind of tired of discovering that MythBackEnd has died overnight and I have lost a days worth of recordings. If necessary I will pull one of my video capture cards. I have enough spare parts around to add it to a different system and try to make that into a slave recorder. (Haven't had much luck with that via knoppmyth so far, keeps wanting to be a front end box. If someone has handy instructions, I would appreciate a post in the how-to forums for that side of the setup.) -Rusty |

having had my share of anoyances with myth-backend freezing, and with the notes above, I stopped into my local MicroCenter today and picked up a SIIG UltraATA 100 PCI card to see if using it would resolve the via dma issues. I don't consider what I have done so far to be a great test of it, but I am a bit happier with it than my previous experience provided. I have been doing transcoding of Dilbert episodes to get them onto SVCDs. At the same time I have been recording two tv shows, watching one of them delayed, and have watched several shows while two other shows were being recorded. I don't thnk MythBackend has run as long as a week without having to be restarted for me on this system. Two days seems to be about the maximum. I figure if it runs for over a month without having to be restarted, that this is a reasonable alternative for people who already have a VIA motherboard. Cost was $29.95 plus tax. I could have gotten a Promise card online for less, but it would have had to wait a couple of days. Instalation was basically a snap, but it does mean that for the moment I am down one slot fan. -Rusty |
