hi andreas : many thanks for your advice. actually, my DVD player support PAL output actually. i guess the bt878 card (pixelview actually) does support the PAL for the tuner but not for the svideo or composite input. it's a grey screen with vertical stripes. i guess i have to study the datasheet a bit. thanks for the advice again. cheers, kai >> hi folks : >> >> i am using a bt878 based capture card and hope to capture the video >> signal out from a DVD player directly via the xawtv. it works perfectly >> for the NTSC signal but not the PAL signal. i tried to alter the NORM >> for the signal but it did'nt work. any comment ? >> >> many thanks >> >> cheers, >> kai >Sure your DVD player supports PAL output? >Had the same problem with a NTSC camera connected to a capture board. The Siemens MXB board >(http://www-c.informatik.uni-hannover.de/~hunold1/linux/saa7146/index.html#supported) >was running fine, switching between PAL (cable tuner) and NTSC (cam on composite-in) worked "out of >the box" with xawtv.
