MythTV is a pretty great product, once you get it working — however, it can be labour-intensive, involving lots of local knowledge to deal with the ins and outs of each area’s TV provider, cable service, etc.
To that end, we’re recently set up a new mailing list: mythtv-ireland, a list for discussion of topics of interest for MythTV users in Ireland.
Particularly on-topic:
the NTL frequencies list for areas in Ireland
hacks to scrape the Channel 6 schedule from their website
dealing with the NTL Digital set-top box
