<DIV>Well, I guess I should have tried some more width and height options. From some advice at the shspvr.com forum, I tried width=640, height=480, and it works...perfect video!</DIV>
<DIV> </DIV>
<DIV>Now, my question becomes: am I going to lose something when I start using TV-out (video quality?) by not having the full NTSC width and height? Is it worth trying to figure out how to get 720x480?</DIV>

I've got a PVR-350 card, am<BR>using ivtv, and have FC1 (more details at the end). Everything's<BR>worked fine up until the point of testing the card's capture<BR>capabilities. I used these commands from the guide:<BR><BR># /usr/bin/test_ioctl -u 0x3000<BR># /usr/bin/test_ioctl -p 4<BR>#
/usr/bin/test_ioctl -f width=720,height=480<BR># /usr/bin/test_ioctl -v input=3,output=1<BR><BR># cat /dev/video0 > /tmp/test_capture.mpg<BR>(ctrl-c to stop capture)<BR><BR># mplayer /tmp/test_capture.mpg<BR><BR>The result is perfect audio but some horizontal (and slightly<BR>diagonal) lines covering the picture of the mpeg. The picture's sort<BR>of there; you can see things moving between the lines...it's like the<BR>image is kind of squished between the lines. I've tried different<BR>"-p" options (0-9) but the result is similar, except some are blank<BR>(I've got 2 different inputs plugged into the card at the moment, but<BR>this was happening when only 1 was plugged in).<BR><BR>The only similar problem I found in the mailing list archive was this:<BR>http://www.gossamer-threads.com/lists/mythtv/users/76958<BR><BR>I tried the advice to set the width to 480 but it didn't help.

to ntsc-cable-hrc but it didn't have any effect.<BR><BR>Other than that, I tried dl'ing the ivtv 0.1.9 source and recompiling<BR>after extracting firmware from the cd-rom that came with the card, as<BR>well as with pvr48wdm_1.7.21188.exe which was dl'ed from the ftp site<BR>mentioned in Jarod's guide.

have any ideas?
