Re: [vdr] Tuning USB
Hello, further investigation shows that it only affects some channels, and only if recording. Meaning: every channel is fine when streamed, some are also recorded, others just cause the vdr process to restart while recording. Any pointers? Better antenna? 2010/2/3 VDR User user@gmail.com On Wed, Feb 3, 2010 at 1:37 PM, Markus Fritsche fritsche.mar...@googlemail.com wrote: Hello, I am using (or trying to) vdr on an Eee PC 701. vdr is set up to be headless, just used for network streaming and (hopefully) recording.

Re: [vdr] Tuning USB
Hello All, The issue was not related to USB whatsoever - my channels.conf was the issue. I created it with scan from the dvb-utils package. Turns out that scan -o vdr outputs the channel frequency in kHz, where vdr expects it in Hz. Obviously, the vdr still tunes but the recording part is baffled. Refer also too: http://www.vdr-portal.de/board/thread.php?threadid=88654 Best regards, Markus keywords: 0 Byte, Recording, Aufnahme, ERROR: video data stream broken, vdr, restart 2010/2/4 Markus Fritsche fritsche.mar...@googlemail.com: Hello, further investigation shows that it only affects some channels, and only if recording.

However, I just want to note that some channels use significantly more bitrate and thus require more bandwidth. This can be a problem when bandwidth may already be near it's limits. ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
