Argh! This is NEARLY NEARLY killed me...
My machine: uninstall everything. Including MC, tv card etc...
I took my TV card into work. Downloaded some drivers, installed them and everything worked 100% perfectly. Mc saw the card and was happy! So was I.
Then I got home. Plugged the TV card back into my PC. Had some issues regarding "Access is Denied" when installing the card. This kept me up all night. Or most of it. Apparently the driver uninstall messes up some permissions in the winxp registry and so it is unable to adjust them. Fixed that by going into regedit and hey presto, they install. These are the drivers that worked, yesterday, no less.
So there I am, testing the card with supplied software. Works. Open MC and hey presto. Disaster.
Before, I got an error saying that the PlaybackEng couldn't find the TV tuner. Now, I get a dialog box that asks me for the current location and whether I'm looking at cable or antennae picture, but the list is empty and the radio buttons don't work. When I press ok, it says, no no... choose a country from the empty list. Ctrl-Alt-Del -- DIE.
I then realise that I haven't run the supplied software. Do that. It asks me for some settings to be set. Ah. Country. Stuff. Tell it. Close that and restart MC -- still no joy.
Complete uninstall of MC, installed the DirectX bugfix (as noted above), complete reinstall...
I have TV working...
WHY WAS THIS SO HARD??? Sorry -- not complaining -- just exasperated!!!
Thanks hugely to those who helped out!
