This is just a quick post for reference. To tune MythTV for Ziggo Digital TV here in the province of Zuid Holland the following settings can be used:
Frequency: 372000000
Symbol rate: 6875000
Modulation: QAM-64
The other settings can be left as ‘auto’
Make sure the decrypt card is in the slot. When I did it I got all the possible channels appear in the list so I had to go through the channel setup and delete all the channels that I don’t subscribe to.
For now I also decided to pull the Electronic Program Guide (EPG) information from the EIT data sent with the digital TV signal. It means I only get a few days of TV schedules (about 4 days) but it meant just ticking an option in the channels setup. Before I used to use the XML TV grabber scripts but the website it was pulled from changed frequently and broke the script, at least with the EIT data it should be a bit more reliable.
