I have a US LVW5045 with upgraded firmware & no hack. It is out of warranty. I am able to record to the HDD, both OTR and using the IEEE cable/AV1 connection. Also, the drive will read/play a commercially recorded disk. My problem is with recording. My drive wonâ€™t finalize a disk (regardless of type/brand) and shows â€œFailâ€ whenever I try. If I use the Guider to view a disk after copying from the HDD, and before trying to finalize it, the 5045 will read the disk only once & show that the copy was successful. However, if I try to view the disk a second time, I get an â€œInvalid diskâ€ message. Any suggestions or ideas would be greatly appreciated.
