and have run into tons of problems. I'm now trying to sort it all out
though I'm not sure I'm attacking them in the right order. Here goes...
<br><br>Ubuntu 6.10 with Myth 0.20 from the distro. Backend up,
frontend up. Added first card, a TwinhanDTV Ter-CI Split (as I'm in
Sweden trying to use DVB-T with Boxer). Scanned for channels and found
all channels ok. Here starts my problems. I can only get a lock on a
few channels (SVT1, SVT2 and SVT24). These are free-to-air but not the
only free-to-air channels. I figure I have a bad signal (strength
and/or qualtity). This seems to be confirmed since same card in WinXP
also gives me lock-problems. But... then I borrow a FireDTV-card from a
friend and it works perfectly (again in Windows, no linux drivers yet).
Hmm, I figure my Twinhan card is bad and borrows another card from my
friend - an identical Twinhan-card. This card gives me only lock on
another channel (TV4) and when I insert my first card again that card
can't lock on any channel.
