[QUOTE="burken, post: 388531, member: 74666"] Thanks a lot for your tips Lotsofjazz. When connecting the TV card directly to the antenna outlet I get around 90% on both signal strength and signal quality. I bought a signal amplifier a few weeks ago and when using the amplifier I get above 90% on signal strength but signal quality drops to around 80-85%. This is on the lowest amplifier setting (+10dB I think). When increasing the amplification the signal quality drops. The amplifier doesn't seem to help with the problem. I have also tried different cables but it doesn't seem to make any difference. I have other problems with my TV card so I think buying a new one will not be a complete waste of money even if it doesn't solve the problem with the HD channel. I have very slow channel switching speed when switching to a channel that is on another frequency/mux and the only drivers that seem to be reasonably stable are from 2006. Newer drivers cause a lot of "cannot start timeshifting/cannot create graph" problems. I borrowed a Floppy DTV card from a friend a few months ago and that card had much better channel switching speed and no driver issues. I didn't test it thoroughly enough to see if it had problems with the HD channel though because at that time I didn't have any good HD codec to test with (that ATI codec available at that time performed badly). Regarding the ATI codecs. Yes, they used to be bad. But with the latest codecs included in Catalyst/Avivo 9.1/9.2 the HD codecs are quite good. I have tried ffdshow and CoreAVC and they don't seem to perform better. burken [/QUOTE]
