Ja habe ich. Leichte patch anpassungen bekomme ich meist auchnoch hin. Wirklich programmieren kann ich aber nicht. Yes I have. I have little skills in patch adjustments (very little). But I'm not a developer so I have no coding skills. Vielen Dank im vorraus für deine Hilfe. Thank you in advance for your help.

Bad image/sound quality with Medion MD 95700
Hi, I tried a Medion MD 95700 with kernel 2.6.32 (for tests: 2.6.30.9) and have a very bad image and sound quality.

Feature Request: virtual /dev/videoX for low budget DVB cards
What about a virtual /dev/videoX for low budget DVB cards? The idea behind is to provide a device set with every type of card (low budget, full featured) so that for example tvtime works with every type of card. The virtual device could be made by the following way: kernel driver (low budget, DVB-Decoded) -> kernel/userspace linker -> userspace decoder -> kernel/userspace linker -> kernel-driver (low budget, DVB-Encoded) I'm not a developer so (maybe) that's just a stupid idea. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
