yes it did, would create empty files randomly. now they are all empty. one
time i got it to record like a sec or two, then it stopped. i noticed this
hdpvr: read: copy_to_user failed
over and over again,when it it attempting to record. i went on the driver
irc channel and was told you get that when the driver is giving info to a
program, but the program isnt answering.
