[vdr] VDR 1.7.20 - Incorrect Progress Bar Times for Radio Programmes

Progress bar display shows excessive times for radio programmes (no video).

A recording of about 5 minutes starts at 5:22:13 and ends at 27404:47:54. The actual recording is fine. Recording is from BBC Radio 3 using DVB-T. ffmpeg -i shows:

Input #0, mpegts, from '00001.ts': Duration: 00:05:06.12, start: 38666.622211, bitrate: 225 kb/s Program 132 Stream #0.0[0x1b6](eng): Audio: mp2, 48000 Hz, stereo, s16, 192 kb/s

I see the same playing with dvbhddevice or xineliboutput.

Recordings made with previous versions of vdr (including 1.7.19 with suggested reversion to 1.7.18 recording code) display correct times playing with 1.7.20.
