Here's a British IPTV mystery: BBC and ITV catch-up works perfectly, but Channel 4 catch-up for same-day programming is always missing — because your IPTV Reseller Panel doesn't understand Channel 4's unique "programme becomes available 1 hour after broadcast ends" rule. A reseller in Stonehouse had British IPTV customers asking "why can I watch last night's Channel 4 shows but not tonight's?" His IPTV Reseller Panel used the same catch-up window for all broadcasters (BBC-style: immediate). Channel 4 has a 1-hour delay after broadcast before catch-up is available. The panel was checking for availability too early, finding nothing, and marking the show as "not available." British IPTV viewers couldn't access same-day Channel 4 programming until the panel's next full EPG refresh (often next day). British IPTV audiences missing same-day Channel 4 catch-up. What actually works is broadcaster-specific catch-up rules. A reseller in Stourbridge switched to a panel that applies different catch-up availability rules per broadcaster — immediate for BBC/ITV, 1-hour delay for C4, 2-hour delay for My5. His British IPTV customers could access same-day content from every broadcaster correctly. The pattern that keeps showing up is that one-size-fits-all catch-up rules fail on broadcaster-specific delays. Ask your provider: "Does your panel support broadcaster-specific catch-up availability windows? What are the rules for C4, My5, and UKTV Play?" If they apply the same rules to all broadcasters, your British IPTV Channel 4 catch-up will always be missing same-day content.
