well, what that patch does is
1. return -EINVAL instead of the unspecific -1 in many cases
2. propagate more errors back to the caller

So maybe you found a bug in vdr or the driver which was there all along but hidden
and maybe harmless.

it would be interesting to know which vdr statement gets that EINVAL from the driver.
Could you find that out?
