I'll give that a try sometime tomorrow or tuesday because I still have some
work to do tonight. :(

I did some quick tests and so far, the stream seems to be ok even though I
tend to get those darn "vpeirq: used 2 times >80% of buffer (65612 bytes
now)" now when doing a switch from xorg <-> virtual terminal. That was the
reason why I used such a high buffer size with the old driver in the first
place and solved the problem by good. This also results in corrupt streams.
But like I said: I only did a few quick tests. I'll give it a closer look in
the next few days and let you know.

You mean reverting budget-core.c to r5541 and lowering the bufsize to 658kb?

Same as with the Cineview above: tomorrow or Tuesday. :)
By the way, just noticed the following:
budget_av: ciintf_slot_shutdown(): ciintf_slot_shutdown
budget-av: cam inserted A
budget_av: ciintf_slot_reset(): ciintf_slot_reset
DVB: TDA10021: tda10021_readreg: readreg error (ret == -121)
budget_av: ciintf_slot_ts_enable(): ciintf_slot_ts_enable: 8
dvb_ca adapter 0: DVB CAM detected and initialised successfully
Those readreg errors have popped up only with the new driver. Before
everything worked just fine.
Sorry for the delay but I'll try to get the rest of the tests you requested
done as soon as possible.
Have a nice sunday,
