Hi Grant
I searched the registry for any settings that can be manually changed and this is what I found: (don't know if it will help)
If you open regedit and navigate to:
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Media Center > Settings > TVConfig
I believe the following subkeys might be relevant: (My signal type is Satellite)
fHasSTB = 1
iBroadcastStandard = 2
iVideoSource = 3
Then if you navigate to same as above but only to Service > Video > Tuners > {some random number} > {another random number} > UserSettings
I have the following: (Seems like this relates to the Satellite setup as explained in the manual that you've downloaded)
EnabledForMCE = ffffffff (Hex)
RecordOrder = 0
RecordPrefered = ffffffff (Hex)
STBCode = <stb> <codeseturl>\microsoft\S0879</codeseturl> <keyinterval>100</keyinterval> <keyduration>xxx</keyduration> <channelpause>yyy</channelpause> <useenter>False</useenter> <numdigits>3</numdigits> <target>\\?\root#system#0001#{7951772d-cd50-49b7-b103-2baac494fc57}\port1\*</target> </stb>
UserDefName = Satellite receiver
UseSTB = ffffffff (Hex)
WatchOrder = 0
WatchPrefered = ffffffff (Hex)
Then if you navigate a little bit further down that hive to TuneRequest > Tuning Spaces
I have:
CountryCode = 27 (For SA)
Description = Analog Auxiliary Input #1
Name = AuxIn1
Network Type = {00000000-0000-0000-0000-000000000000}
I don't know if yours should be the same. It's something you can play around with but I recommend making a backup of your registry first.
Regards
