Samsung R155 Recording from VHS Issues
The reason why you are having this problem is because you haven't finalized the disc. In able for you to play that Burned DVD that you have you need to Finalized the disc.
Finalizing a recordable optical disc means writing the disc's lead-in (the Table of Contents or TOC) and lead-out information (blank data that fills up the unused space at the end of the disc) so that a DVD player will know where the various tracks begin and end. Without the TOC, a conventional DVD player will not be able to read the contents of the disc.
Once the disc is finalized, no more information can be written to it. Finalizing takes about two or three minutes.
To finalize a DVD-RW/DVD-R:
1. Press the Menu button with the disc stopped.
2. Select Disc Manager and press Enter or the right arrow.
3. Select Disc Finalize and press Enter or the right arrow.
You will be asked twice if you are sure that you want to finalize the disc. Select Yes and press Enter.
Once the disc is finalized, you cannot delete entries from the record list. After being finalized, the DVD-R/DVD-RW (video mode) operates in the same manner as a DVD-Video. Recorded discs must be finalized in order to play back in non-Samsung DVD players.
A DVD-RW disc that has been recorded by DAO (disk-at-once mode) in a PC cannot be unfinalized.
A DVD-RW disc that has been recorded in Video Mode on a non-Samsung recorder cannot be unfinalized by a Samsung recorder.
A DVD-R disc cannot be unfinalized.
Note: Finalization does not apply to DVD-RAM.
If you cannot finalize a DVD-R or DVD-RW disc, make sure that Disc Protection is turned off. If you are still having difficulty, you may try calling technical support of SAMSUNG.
Note: Do not turn the recorder off while it is finalizing the disc. Data on the disc will be damaged if the finalization process is interrupted.
