This pull request introduces several performance optimizations and behavioral improvements to input event handling, EPG grid rendering, and configuration of input devices. The most significant changes include batching and intelligent processing of input events to avoid repeated key handling issues, implementing row-level caching in the EPG grid to reduce unnecessary redraws, and using device-specific repeat/delay timings for remote controls. Additionally, EPG selection UI updates are now rate-limited for smoother navigation.

Input Event Handling Improvements

• Modified eRCInputEventDriver to batch input events, queue them, and deliver at most one key event per main loop iteration. This prevents repeated key events from being mishandled when the UI redraws slowly and ensures proper processing during screen switches. [1] [2] [3]

EPG Grid Performance Enhancements

• Added a row-level cache (rowCache) to EpgListGrid so that only the selected row is rebuilt every redraw; other rows are reused unless their data or geometry changes. The cache is cleared on relevant data/geometry changes and limited to a maximum size for efficiency. [1] [2] [3] [4] [5] [6]

Input Device Configuration Improvements

• When configuring input devices, the system now queries and uses the actual repeat/delay timings from the device (if available) instead of hardcoded defaults, ensuring better compatibility and user experience. [1] [2] [3] [4]

EPG Selection UI Responsiveness

• The EPG selection screen now rate-limits updates to selection info (event details, service, etc.) while the user holds navigation keys, reducing unnecessary redraws and improving perceived responsiveness during fast navigation. [1] [2] [3] [4]
