Quest for saving Biathlon recordings

Tuesday, December 4th, 2007

Last Thursday and Friday as usually I’ve recorded some TV shows of Biathlon 2007/2008 season’s first World Cup event’s, using my TV Tuner’s Winfast PVR software, as mpeg2 stream. Then authored to DVD as usual and boom – audio is out of sync (while mpeg2 file played on Windows Player Classic without any audio sync problems). Tried again with selecting right first and the last frame – the same. Tried another file – the same problem. Damn! Then I remembered that Cross Country event, which I’ve recorded on 24th of November, made as DVD had audio sync problem. But I haven’t investigated that time, as I already had deleted the source file.

After one day of investigation, in one forum I’ve found, that the newest Winfast PVR software (ver 3.1.1.8), which supports my TV Tuner is buggy. I’ve tried to rollback to one version back, this had the same problem. Then later took software from installation CD (ver 3.0.10.12), some long tests again and wow – it works! The first step then was complete, I could record mpeg2 stream from TV without audio sync problems.

The second step was more complicated – I still couldn’t author already captured mpeg2 material without audio sync problems. Once again searched over Internet, tried several mpeg2 editors (mpeg-vcr, virtualdub with mpeg2 support, etc.) and finally found one which done brilliant work – VideoRedo, using “QuickStream Fix” procedure from “Tools” menu – it fixed mpeg2 stream, so I could properly author my mpeg2 material to DVD.

Ooh! My biathlon has been saved :)
