... Also, what are you using to play the videos and what are you converting them with?
Hi Oldschool297:
As wither 3 requested, it would be helpful if you could let us know which browser and/or media player you are using to try to play these problem 720p videos.
If you haven't tried Mozilla's
Firefox ESR v52.9.0 browser (the final legacy version for Win XP and Vista released 26-Jun-2018), full offline installers (all regions and languages) are available for download from Mozilla's FTP server at
Directory Listing: /pub/firefox/releases/52.9.0esr/win32/ (
note that 32-bit Firefox ESR is recommended for both 32-bit and 64-bit Vista SP2). If you want the English-US installer (Firefox Setup 52.9.0esr.exe), for example, choose the /EN-US subfolder. Firefox ESR v52.9.0 supports TLS 1.1 and TLS 1.2 protocols for connecting to secure https sites by default, and I would recommend that you
add the latest TLS 1.3 support to your Firefox ESR v52.9.0 browser [i.e., by changing security.tls.version.max to a value of 4 (TLS 1.3) in the advanced browser settings] as instructed in Martin Brinkmann's June 2017 ghacks.net article
How to Enable TLS 1.3 Support in Firefox and Chrome.
A third-party media player like VideoLAN's
VLC Media Player might also play your videos correctly.
Do you know if your Vista SP2 was patched to the end of extended support (11-Apr-2017) before Microsoft deactivated the Windows Update servers for Win XP and Vista in August 2020? If you aren't sure that Windows Update delivered the last batch of security updates for Vista SP2 in April 2017 open your IE9 browser, go to Help | About Internet Explorer, and see if IE9 was patched to
Update Versions 9.0.60 / KB4014661 (
Cumulative Security Update for Internet Explorer 9: April 11, 2017) as shown below.
