Hello! I see you're asking about the maximum recording duration in the UHF app. To help you best, could you please clarify if you're referring to recording IPTV streams within the UHF app itself, or are you asking about recording duration limits on UHF Server or another related component? Also, are you experiencing any specific issues when trying to record longer programs?

From general knowledge, the UHF app works as an IPTV player with recording capabilities, but the exact maximum recording duration often depends on factors such as your device storage, server settings, and network stability. Some users have noted that recordings sometimes get cut short compared to the scheduled program length, especially on certain platforms like Linux.

If you want, I can guide you through checking your app's recording settings and storage availability on your Windows machine (since you're on Windows 10), or help verify if the server settings are limiting the recording time.

Would you like to proceed with checking these, or do you have any more details to share?
