    Last wk i recorded 2 shows that when i played the pic was staticky - you know they look like the broken up picture when theres a thunderstorm.
    I then recorded a live tv show that the pic was ok on - then played it - same thing staticky.
    Tried some previous saved recordings - all played ok.
    So did a reboot.
    Recorded same channel again - all ok now.
    Since then have done 50+ recordings - all ok.
    Anyone ever have this ??

    Haven't experienced this.

    No, I don't know. Have a pic? A video might even be better. You could upload it to YouTube. Is it dropping frames and looking stutterery or is is there major MPEG artifacting/macroblocking or something else?

    Or, are you getting random small dots? If it's random small dots, then it's likely a case of HDMI "sparklies" or "sparkles" like Why all HDMI cables are the same. That's usually a case of signal loss over the cable. I've personally witnessed those with too long an HDMI and/or DVI cable run.

    Yes

    Dont remember - like i said it happened just that time & hasnt happened again in over a wk

    That's usually a case of signal loss over the cable.
    But again i taped a channel that had a perfect pic on live but when i switched to its recording it was broken up.
    If its the cable why was the live ok

    Not 100% positive since it doesn't happen here. We also don't get many thunderstorms and the odds of me correlating recordings w/thunderstorm activity are low.

    If the lightning is severe and happening frequently (very rare), I unplug most of my electronics including my TiVo to prevent possible lightning damage.
    It's possible the reboot caused your TiVo to output in a different resolution which might affect something.

    Often, if I reboot my TiVo Bolt+, TiVo falls back to 720p resolution after a lot of green flashing. I hit this today. I have to manually switch it back to output 1080i.

    I also can repro this due to a known Yamaha receiver-related bug (for which the workaround by changing setting on the receiver doesn't work). To prevent the fallback to 720p from happening, I MUST either power on my TV and wait a bit (e.g. for its UI telling me HDMI 2) before turning on my receiver or vice versa: power on receiver, wait for a relay inside to emit a click then turn on my TV. This problem I also had when I my TiVo HD was my active TiVo. The easiest workaround then was to skip HDMI for video and use the component video outs, but Bolts don't have that.
