Hi,
Ok, as far as I can see, I've been offered three different solutions -
thank you so far:
1. getting the latest drivers from hg - ehem, what do you mean by "hg"?
Do you have a link?
2. applying sth like this:

-- a/linux/drivers/media/dvb/bt8xx/dvb-bt8xx.c	
 	case BTTV_BOARD_NEBULA_DIGITV:
 	case BTTV_BOARD_AVDVBT_761:
 		card->gpio_mode = (1 << 26) | (1 << 14) | (1 << 5);
		card->op_sync_orin = BT878_RISC_SYNC_MASK;
- 		card->irq_err_ignore = BT878_AFBUS | BT878_AFDSR;
+ 		card->irq_err_ignore = BT878_AFBUS | BT878_AFDSR | FDSR;  // changed!!!
 		/* A_PWRDN DA_SBR DA_APP (high speed serial) */
 		break;

3. applying this patch:
http://article.gmane.org/gmane.linux.drivers.dvb/20005/raw

First question: all three possibilities at once or one after the other?
And which one first?
- Shall I remove my changes to "bt878.c"?
- And what about my new observation concerning the SCERR-message?

thanks
Jörg
