PixelView PlayTV MPEG2/TVision TVF5533MF Tuner | |

I have a PixelView PlayTV MPEG2 capture card with FM and remote that I'm trying to set up. It has a Conexant BT878A chip and a TVision TVF5533MF tuner. I can get the card to work using composite input, but I can't get the tuner to work. After much searching, I found that the TVision tuner is actually made by Young Mountain Electronics Co., http://www.ymec.com.tw, and I found some basic specifications for what should be a similar tuner, the TVF8531MF, at http://www.ymec.com.tw/tvf8531-mf.pdf. I've sent a request for specs for the 5533, but haven't heard back yet. >From what I can tell, the TVF8531 uses the Philips API, but I can't get any tuning no matter what I choose in the tuner= option. Also, the specs seem to say the tuner defaults to address C2 unless the address pin is biased to a fixed voltage, and I think there is an empty resistor pad to ground on the address pin, but I haven't checked with a multimeter yet. If the pad was filled, the address should be C0, but since it is not, I think it should be C2. But when the tuner module initializes it says it finds a chip at C0. I tried forcing the address to C2 in the module, but that didn't help either. Does anyone have any ideas on where I should go next? Does anyone else have this card working, or is anyone working on it? ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/ -- Unsubscribe mailto:video4linux-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list
