TVAnytime has its own set of data descriptors to handle late-running +or cancelled programmes but these are not used by Freeview Plus. Instead the +Running Status from the now/next section of the EIT is used to start and stop +the recording. + +VDR can control timers from the running status by using 'VPS' functions in +conjunction with this patch. Note however that the normal VPS operation will no +longer work. + +To use VPS for accurate recording, some conditions must be met: + +- VDR must be compiled with the 'VPS Fallback' patch (included with this + plugin). Note that some Linux distributions (esp. Mandriva) include this + patch in their binaries. +- Parameters 'UseVps' and 'VpsFallback' in setup.conf must both be set to 1 +- Timers must have the 'use VPS' flag set +- The start time of a timer must be set to exactly the scheduled start time of + the programme (ie no padding). + +With these conditions met, the sequence of events is: + +- Shortly before the scheduled time of the recording (set by 'VpsMargin' in + VDR's setup.conf) VDR switches to the multiplex containing the channel to be + recorded +- VDR monitors the running status of the programme to be recorded +- When the running status changes to 'running', VDR starts recording +- When the running status changes to 'not running', VDR stops recording and + deletes the timer. + +CAUTION - VPS recordings seem to have a lower priority than live viewing. VDR +will not interrupt live viewing to start looking for the start of a recording.
