Hello everyone,<br><br>I need your help. I have just bought a brand new Nova-TD-500 card
and have found the signal strength (and therefore picture quality) to
be unexplainably low when watching live TV. There are significant image artifacts and glitches.
Does anyone have a list of steps to debug this problem. This is what
I've tried so far:<br>
<br>1) Plugged co-axial cable directly into TV (i.e. not via MythTV) -> Get good picture therefore no problem with cable.<br>2) Tried a antennae signal booster -> No luck.<br>3) Tried DVB in Kaffeine and Xine as well a MythTV -> All give bad TV image.<br>
4) Tried pugging the co-axial cable into socket 1 then socket 2 then socket 1 and 2 (this card
has two inputs for some reason) - My TV signal strength doesn't get
over about 56% and I get different results depending on what socket I
plug the coaxial cable into. If I plug it into the bottom input (the
one closest to the IR port) I seem to get a slightly better signal on
one tuner but ZERO-SIGNAL on the other but if I plug it into the top
input I get equally poor signal on both tuners.<br>
5) Looked at whether DMA is on -> Yes, I'm using a SATA HDD.<br>6) Experimented with the "force_lna_activation" and "buggy_sfn_workaround" module options -> No luck.<br>7) Compiled with VDPAU and checked CPU usage with "top" -> CPU usage is <5% so no performance bottleneck.<br>
<br>If I can't think of anything else I'm going to take the Nova-T card back to the shop as faulty?<br><br>Cheers,<br>Tom Fotherby<br><br>P.S. My hardware is a ASUS P5N7A-VM motherboard (with a onboard nvidia GF 9300) with a 3GHz dual-core CPU and 2GB of RAM. Nova-TD-500 PCI tuner card. Display: Panasonic Viera TX-26LXD6A LCD TV.<br>
