Guest Graham Posted October 25, 2008 Posted October 25, 2008 I have a pci tv card , twinhan, but ive never mamanged to run any software except the original install disk ... now .. when i view sky news on ch82 , the pog locks and shuts down , sending a error report as well If I download the latest drivers etc from the web site .. everything installs and works .. but the audio and video are slow , juddery , and prone to periods of lock up .... Any one any ideas . appart from ditch the card .. ?? the system is a intel P4 3.2 Ghz , pf21-ext m-board - 250 mb pci-ext navidia video card ... 2 ghz ram ... not sure if its dual core .. shows as 2 cpus on the device driver list ... winxp-pro all the other prog's run fine ... media players , dvd video ..no problems .. everything is up to date ...
Guest R. McCarty Posted October 25, 2008 Posted October 25, 2008 Re: PCI twinhan dtv Which PCI slot is card installed in ( Count from the Video - either AGP or PCIe ). Usually most motherboards only provide one or two slots with independent IRQ mappings. The sluggish response may be due to IRQ sharing. While XP can handle this in normal situations, there are some cards that do not perform well when they are used in a "Shared IRQ" setup. Most motherboard manuals have a IRQ map show how the slots are hard wired.

In addition to the possibility of an IRQ issue, you may want to consider what the software is doing with the data. On some TV cards, they do it like this - ******* Preview video only, or Preview video and record at the same time TV_Card ----- DMA_PCI_Bus --+ +--- Copy_to_video_card_frame_buffer | | Write_To_Disk Read_From_Disk | | (DMA_PCI_Bus) (DMA_PCI_Bus) | | Disk_Drive_for_PVR_Data ******* Record video only (no preview, just record it) TV_Card ----- DMA_PCI_Bus --+ | Write_To_Disk | (DMA_PCI_Bus) | Disk_Drive_for_PVR_Data ******* Playback pre-recorded video (doesn't use the card at all) +--- Copy_to_video_card_frame_buffer | Read_From_Disk | (DMA_PCI_Bus) | Disk_Drive_for_PVR_Data ******* In those examples, "preview" or "live viewing" can be stressful because of the datarates involved. For example, if the Disk_Drive_for_PVR_Data was connected to the SIS180 chip on the PF21 Extreme motherboard, there could be multiple 20MB/sec streams of data on the fly. Try recording video (without looking at the images), then try playback of that recorded content, and see if it is smoother. Paul

Ok thats a good point .. at this momnet I dont know which slot its in ..I will have a look at the book , the mother board has 3 pci slots, listed as 32 bit , pci 2.3 , 133mb/s max throughput ... and qty 1 pci express x16 (pci-e1) which has the video card in it I dont see any referance to the use of the 3 pci slots ... only two are white and the middle is yellow .. if that means anything ?? tnx - G ..
