As long as VDR doesn't report any "missed data blocks" it should have
taken all the data fast enough. VDR checks the sequence numbers of
the data blocks and also their lengths. Also: if the glitches happen
at different points when replaying, ths would indicate that the recorded
data is ok, but the driver/firmware has trouble keeping picture and sound
in sync.
