#2582: buffer underflows ecoding HD video to ntsc-dvd -------------------------------------+------------------------------------- Reporter: SullaFelix | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Since upgrading to v1.0.5 (and now 1.0.6) I've been getting hundreds of buffer underflows converting my HD video to DVD format, specifically NTSC format. I don't do anything special to the video to encode them and even video I've successfully encoded before are giving underflows when before they encoded cleanly.
